Screen pause at program end in C

I want to do something line by line Press any key to exitat the end of the program, but could not figure out how to do it.

When I run my program, the terminal exits before I see the results.

//by Nyxm
#include <stdio.h>

main() {

    int temp, x, flag, num, size;

    printf("\nEnter how many numbers you wish to enter: ");
    scanf("%d", &size);
    int array[size];

    for (x = 0; x < size; x++) {
        printf("Enter an integer: ");
        scanf("%d", &num);
        array[x] = num;
    }

    printf("Please enter either 1 or 2\n1:\tAscending\n2:\tDescending\n\n...");
    scanf("%d", &num);

    if (num == 1) {
        flag = 0;
        while (flag == 0) {
            flag = 1;
            for (x = 1; x < size; x++) {
                if (array[x] < array[x-1]) {
                    flag = 0;
                    temp = array[x];
                    array[x] = array[x-1];
                    array[x-1] = temp;
                }
            }
        }
        } else {
        flag = 0;
        while (flag == 0) {
            flag = 1;
            for (x = 1; x < size; x++) {
                if (array[x] < array[x-1]) {
                    flag = 0;
                    temp = array[x];
                    array[x] = array[x-1];
                    array[x-1] = temp;
                }
            }
        }
    }

    printf("\nYour sorted array:\n");
    for (x = 0; x < size; x++) {
        printf("%d\n", array[x]);
    }
}

Any suggestions?

I use in , if that matters. MonoDevelop Wubi

To make this quick hack, two options are most common:

/* Windows only */
#include <stdlib.h>

system("pause");

and

/* Cross platform */
#include <stdio.h>

printf("Press enter to continue...\n");
getchar();

I suggest the last method, although the first method really launches "any" key, and the bottom only starts when you enter.

Use getchar():

...program...
printf("press enter to continue...\n");
getchar()

getch() ( _getch()) , , getchar().

getchar() , "enter". getchar() , -.

getch() : , , , "enter". , .

, :

system("pause");

getchar() - , , scanf, '\n' - . . getchar() enter scanf()?

: 1) ( "" ); 2) getch(); 3) getchar();

This is an old question, but I thought I would add a method that I use when testing programs in a Windows window.

Compile the program in exe. Then create a script package to wrap the program line by line:

@echo off
foo.exe
pause
exit

which will execute your program, as it should be, without any dirty hacks, allowing you to pause the window and see the result.

if we use getchar();, getch();or system("pause");when we open the debug folder and run the .exe file, it still ends immediately :)) I use cin >> variable;this certain pause of the screen :))
