How do you delete the items in an array in c++? (an example would be appreciated.?

These are the 2 possible ways





Sentinel Value :


-------------------------------


Declare a sentinel to indicate if the value at a position is deleted or not.





1. Assume that an array can hold +ve integer values


2. if u want to delete array[10] then


just change its values to a -ve value ( -1 for example )


3. So when traversing the array if u encounter a -ve value it means that the value is deleted.





Shift %26amp; Mark :


-------------------------------


Use a variable to indicate the end of array.





1. Ur Array holds 100 values currently so


Array_End = 99 ( 0 - 99 = 100 )


2. If u want to delete array[31] then


Shift Array[31] = Array[32] = Array[33] ... Array[Array_End];


( i:e u shift the array contents to the left )


3. Update the Array_End to point 1 position to the left


( Array_End --)





These are static ideas of deleting array values.


But to have a dynamic control u need to use the new / delete operator or use a link list as an array.





Hope this helps u in getting an idea.

Event programming: providing handlers for application events called by the operating system. Game programming only (???) using functions and arrays *and variables* in C++: could be considered lower-level game programming, since many game makers are even more higher level unless you compare with assembly language or machine code.

How do i remove an element in a c++ array when the array is predetermined?

//say i have a class called Employeetype





//my Employeetype contains an int id, float salary, string last_name, string first_name





Employeetype employee;





employee[30];





//i read the employees in from a file and i have one i would like to remove. i have to remove that employee then shift all the employees down to fill in that space.





//srry im a beginner and need help i need the most simple way possible








//thnx guys

How do i remove an element in a c++ array when the array is predetermined?
You will have to set the element in the array to null, then loop through the rest of the array, moving each up (loop element - 1) until you reach the end of the array.





I have included a link to a site which shows you some great basic array manipulation. Scroll down to the section titled "Inserting" and you will find some code that shows you the moving up of items after an insert. The same thing will apply when you remove an item. Everything below the delete will then move up to take the space of the deleted item.





Just remember that after all items are moved up that the last item is set to null so that you won't have to items that are the same and you have a null that can terminate a loop through the array.





Check out the link and I hope it helps! Good luck!

C++ 2 dimensional array, grade thing?

I'm sick with the flu and pretty tired so it's really hard to focus on these difficult problems. Anyway, could someone please tell me how to do the following problem? It goes like this: A teacher has 5 students who have taken 4 tests. The teachers uses the following grading scale to assign a letter grade t a student, based on the average of his or her 4 test scores. Testscore 90-100 is an A, 80-89 is a B, 70-79 is a C, 60-69 is a D, 0-59 is an F. The is asks, write a program that used a 2-D array of characters to hold teh 5 student names, a single-dimension array of 5 characters to hold the 5 students's letter grades, and 5 singl-dimension arrays of 4 doubles to hold each student's set of test scores. The program should allow the user to enter each student's name and his or her 4 test scores. It shoudl then calculate and display each student's average test score and a letter grade based on the average. Input Validation: do not alow scores higer than 100 or less than 0

Hey guys n gals need someone good in c to take on this one will send u my feedback after ur result thanks?

How can one Implement a function in C that takes an array of integers,%26amp; and reverses the order of items in the


The function you implement must have the following form:


void reverse_order(int array[], int n)


{


/* your code goes here: re-order the n items in the array so that the


first one becomes the last


* * and the last one first.


*/


}


You should then implement a main() function which reads in a set of integers into an array,


reverses the order of the number (using the function you have just defined) and prints them out


again.


For example, when complete and compiled, you should be able to run your program, and enter


the numbers:


2 4 5 11 23 1 4


then program will then print out:


4 1 23 11 5 4 2





make sure your program will allow the user enter the numbers and then gives the output as their reverse

How to pass an array(by reference and by address)in C/C++?

Give a program code illustrating the difference between passing an array by reference and by address..

How to pass an array(by reference and by address)in C/C++?
1. In C you pass arrays by reference by default. You pass everything else by value by default.


Passing by reference and passing by address are the same thing. In C, to explicitly pass by reference, when it isn't an array you declare it with:





int Myfunc(int *MyVar);





then in the main() function you call it with:





Success=Myfunc(%26amp;MyVar);





In other words, Myfunc takes a pointer to or address of MyVar (*MyVar) and you actually send it the address (%26amp;) when you call it.





With C++ all you need is that address operator. You declare:





int Myfunc(int %26amp;MyVar);





then in main() you call it with:





Success=Myfunc(MyVar);





But arrays are always passed by references, and that means passed by addresses: They are the same thing.





I'm not citing Kernighan and Ritchie's the C programming language in this answer, our Stroustrup's the C++ programming language but if you don't have them GET THEM.
Reply:Don't listen to Rowell A, Visual Basic is a crap language compared to C++, but enough of the jibber jabber about which language is best.





Array's in C++ are pretty easy to understand once you get the basics down.





For a full explanation of how to pass an array to a function via reference, go to this website: http://www.cplusplus.com/doc/tutorial/ar...





Once you are on that site, scroll down to the section that reads: "Arrays as parameters".








In basis, passing an array to a function is practically the same as passing a variable to a function, but you add the elements of the array (the number inside the brackets ([ ])).








EDIT__________________________________


Very well said jplatt39, i gave you a thumbs up :) I haven't fully gotten up to pointers in my self education of c++, I just got up to building basic structs and dealing with vectors. I haven't gotten passing and whatnot down completely (pointers haven't been learned yet). I will learn them soon though :)

You mean reverse the ordering of elements in the array (e.g., (1, 2, 3) -%26gt; (3, 2, 1))?





If so, you'd iterate up to half the length of the array, and exchange array[i] with array[length - 1 - i]

C++: Adding user inputs into a C-String Array?
3paul is correct. It would be much easier if you simply use the Standard Library class 'string'. I don't understand why you don't want to use it, unless your instructor is forbidding it. I'm also confused with your term C-String. It sounds like the MFC class CString (which you should not be using).





If you do use the Standard Library class string, you can simply declare an array of string:





string name_list[10];





// your stuff


cin %26gt;%26gt; name_list[0];


// etc.





Even better, if you use the template vector, you can have a variable sized array:





vector%26lt;string%26gt; name_list;


string input;





do {


cout %26lt;%26lt; "Enter name (blank to stop)\n";


cin %26gt;%26gt; input;


if (!input.empty())


name_list,push_back(input);


}


while (!input.empty());
Reply:char name_list[9]; does not create an array of 10 character strings. It's an array of 9 (not 10) characters. Period. So when you reference name_list[0] in the cin.get call, you're referencing a char, not a char*.





Now, char* name_list[9] would create an array of nine character pointers, but they wouldn't automatically point to character strings either. That's more detail you'd have to work out.





Hope that helps some.
Reply:You have name_list as something like a "string" right now instead of an array of "strings." Try char name_list[9][100].





But you can just do this with std::string which would make your life much simpler, and you're using the newer standard library stuff anyway so shouldn't make much of a difference in overhead. You'd probably prefer to just go that route.

Implement a function in C that takes an array of integers,& and reverses the order of items in the array?

The function you implement must have the following form:


void reverse_order(int array[], int n)


{


/* your code goes here: re-order the n items in the array so that the


first one becomes the last


* * and the last one first.


*/


}


You should then implement a main() function which reads in a set of integers into an array,


reverses the order of the number (using the function you have just defined) and prints them out


again.


For example, when complete and compiled, you should be able to run your program, and enter


the numbers:


2 4 5 11 23 1 4


then program will then print out:


4 1 23 11 5 4 2

C++: What's the easiest way to put the filenames of a directory in an array?

I'm using a Microsoft Visual Studio 2005 MFC application.





I would like go through a directory, reading file names. If the file name (not including extension, of course) is three letters long, I would like to put that filename into an array, and then move on to the next file to test whether it belongs in the array, until I've reached the end of the directory. What is the easiest way to do this? Should I use a CFileFind, or is there a more efficient method?





Specific examples would be appreciated. Also, please keep in mind that this is an MFC application: NOT a console application.





Thanks!

C++: What's the easiest way to put the filenames of a directory in an array?
Doesn't matter if console or not, you still can use console techniques, just need to modify to fit your instance.


for the cout, replace that with your array, I would recommend a dynamic array or better yet use a vector class so you don't have to worry about allocation





CFileFind finder;


BOOL bWorking = finder.FindFile("*.*");


while (bWorking)


{


bWorking = finder.FindNextFile();


cout %26lt;%26lt; (LPCTSTR) finder.GetFileName() %26lt;%26lt; endl;


}
Reply:Ugh...Truthfully, I'd recommend that you program Windows with the Windows API instead of using the stupid Microsoft MFC or Borland VCL frameworks because they both produce incredibly bloated, slow code. They also don't teach you how to really program the operating system since they are bloated, slow wrappers which EVENTUALLY calls the Windows API functions. Anyways...





The 1st thing that comes to mind is the size of your array. Normally, you would have to write code so that the allocated memory block or array for the file names is large enough for a good number of file names (this can waste memory), or you have to write code that will dynamically allocate another block of memory when your 1st buffer gets full. Something to keep in mind...





As far as getting the file names, do something like this:


1) Call CFileFind::FindNextFile(). Set a flag if it returns 0 (last file in directory).


http://msdn2.microsoft.com/en-us/library...





2) Call CFileFind::GetFileName().


http://msdn2.microsoft.com/en-us/library...





3) In a loop, read the file name and copy it to array/memory block if necessary.





4) If the flag wasn't set, go back to step 1.

How can use class or structure and dynamic arrays for following problem and how to sort the aggregrate marks w
If you have access to STL, you could use a multi-map to store the aggregate along with the names as the key and the rest as the value. Eventually, you would print out the results in the right format. You could use a comma separation between various values in both the key and the value.


You could also store the name with the marks in a class and create such objects to a vector. A sort function on this vector should give you the required result, provided you define your operator%26lt; appropriately.

Please ....

How to write a function (reverseDiagonal) that reverses both diagonals of a two dimensional array (in c++) ?
Here is how you would walk one diagonal. The other is just an simple modification of the first walk.





for (int r =0, c = 0; r %26lt; HEIGHT/2 %26amp;%26amp; c %26lt; WIDTH/2; r++, c++){


swap( array[r][c] , array[HEIGHT - r - 1][ WIDTH - c - 1] );


}





For the second you do essentially the same thing but you would initialize it differently, invert the test for c, and decrement c instead of incrementing it.





for (int r = 0, c = WIDTH -1; r %26lt; HEIGHT/2; c %26gt; WIDTH/2; r++, c--){


swap( array[r][c], array[HEIGHT - r - 1][ WIDTH - c ];


}





You could avoid some of the math by adding two other variables that started at the opposited corner and then moved in. Your test would then be to see when their values crossed.


Here's how that would look with the first loop





for (r_0 = 0, c_0 = 0, r_1 = HEIGHT - 1, c_1 = WIDTH - 1; r_0 %26gt; r_1 %26amp;%26amp; c_0 %26gt; c_1; r_0++, c_0++, r_1--, c_1--){


swap(array[r_0][c_0], array[r_1][c_1]);

How do you check if a spot in a char array has a character there or not (C++)?

I'm having problems couting a character array. It couts the list of characters, plus a bunch of junk after it. So then I need to set up a while statement...





bool notChar = false;


int count = 0;


while(notChar = false) {


cout temp[count];


count++;


if(temp[count] == ???) { notChar = true; }


}





...Any ideas?

How do you check if a spot in a char array has a character there or not (C++)?
char* or char[ ] types typically use a char value of 0 to mark the end of the string.





however, "cout" will stop at this 0 automatically, so you obviously do not have a 0 at the end of the string.





the best bet would be to not use a char* or char[ ] type at all, but use a STL::string type. research the C++ standard tempalte libraries. it has a string type with everything built in.





if you must use char* or char[ ], initialize your array to all 0's and never use the final size'd spot. this is clumsy C programming though, not C++. Use the STL in C++, it prevents many bugs.
Reply:look up isalpha





something like





if (!isalpha(int(temp[count])) notChar = true;

"C++ : should main() b defined compulsarily"





Not sure what you mean.





"can it b inside a class?"





Not in C++, no it must be global. You can do this though:





int main(int argc, char **argv)


{


return Program.Main(argc, argv);


}





static class Program


{


static int main(int argc, char **argv)


{


return 0;


}


}





"also in array c[]={1,2,3} what will be c[1]?"





Arrays in C are 0-based, so c[1] is the second element, in this case the value is 2.





The rest of your questions sound like homework and I'm not going to ruin your learning experience.

Finding Biggest Value in array (C Programming)?

I have integer data in data.dat. Assume the data b[19] = {1,2,3,4,5,6,7,8,9,10,9,8,7,6,5,4,3,2,1}... Then I write the program to read the data from the file. Success! but, I can't find the biggest value. This is the part of finding the biggest value:





a=0 /*init value of a = 0 so it can check the value below*/


for(i=0;i%26lt;19;i++) /*20 data in the array of b*/


{


if(a%26gt;b[i]){ /*check the condition*/


printf("This is the biggest value: %d\n",a)


}


a = b[i]; /*store the current value of b to a so it can check in the next loop*/


}





but i get back these result:





This is the biggest value: 10


This is the biggest value: 9


This is the biggest value: 8


This is the biggest value: 7


This is the biggest value: 6


This is the biggest value: 5


This is the biggest value: 4


This is the biggest value: 3


This is the biggest value: 2

B. Write a function called push that will insert an integer into the array.


C. Write a function called pop that removes the top-most element in the array.


D. Write a main function that takes input from the user based on integers: 1 - PUSH; 2 - POP; 3 - EXIT. Whenever


the user enters 1 (for PUSH), the integer that follows it is the element to be pushed.

In C# how do I search an array to see if it already contains a particular number?

The user enters a number. I have have to search through the array to see if it already contains this number. If it does, then it will be disregarded so that their are only unique numbers in the array. If the number is not already in the array, it will add it to the array.





I have the array already denifined by the number that the user inputs, I just do not know how to search the array to see if that number is there or not. I was using if statements to compare the number to each element of the array, but that would get rid of both copies of the number instead of keeping one. Please help!

In C# how do I search an array to see if it already contains a particular number?
With Array.IndexOf you can easily check the existence of an element without using predicates. Use the following code as a guideline:





type[] myArray = whatever;





if (Array.IndexOf(myArray, theNumber) != -1)


{


// The number already exists in the array


}


else


{


// The number does not exist in the array


}
Reply:I don't know C#, but here's pseudocode:





boolean isInArray(int array[], int number)


{


for (x=0; x%26lt;=array.length;x++)


{


if (array[x] == number)


return true;


}


return false;


}





Then call that method in another function to put the number in or not depending on if it's true or not. You would also want to use a Vector (i'm not sure about C#'s array abilities but arrays are typically static meaning you can't add more elements after it's declared) so you can dynamically add more elements for as long as the person inputs numbers. Vectors work roughly the same way as arrays, but the number of elements can be dynamically changed. That and the vectors will have their own methods (at least they do in Java which C# imitates).

How do I make a C program?

How do I make a C program that solves a system of three linear equations with three unknowns using determinant of the third order (3*3). Be guided by the following:


1. Use two dimensional arrays in programs.


2. Prompt the user for the input of numerical coefficients and constants of the three equations.


3. The program must contain at least three functions (not including main):


a. A function that computes;


b. A function that displays the matrices; and


c. A function that temporarily stores and replaces values in the matrices ;


4. The program should display the four matrices and the values of the three unknowns should be displayed.

In C++, if i have 2 lines of integers separated by spaces from a source file, how do i read them into 2 arrays
are they guaranteed to only be one digit? If so, you could use getc - get character. Otherwise, you could use gets - get string and use strtkn() - string token and break up the string based on spaces, or you could walk through the string yourself.

Can someone explain arrays easier then this?
I think learning by example is the easiest.





int myArray[3] means you have declare an array call: myArray and the data type is integer and total capacity of it is 3.





It is just like you declare a normal variable, just that array simplify your programming.





You could declare the 3 integer variable to store the values instead of an array but practically it is too much work and hard to maintain.





So, an array is an easy way for you to store related data using the same variable array name.





Example:





int myBankAccount1, myBankAccount2, myBankAccount3;





as compare to: int myBankAccount[3];





Now let say you need to initialize each bank account to start with 0:





so in the coding:





myBankAccount1 = 0;


myBankAccount2 = 0;


myBankAccount3 = 0;





and in array case:





for(int i=0; i%26lt;3; i++)


myBankAccount[i] = 0;








Now imagine you are dealing with 10,000 bank accounts. Then you will realise you have to use Array to handle it better than just declare 10,000 variables.
