Pause screen at program completion in C

Question

I want to be able to do something along the lines of Press any key to exit at program completion, but have no been able to figure out how to.

When I run my program, the terminal exits before I can 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 am using MonoDevelop in Wubi, if that makes any difference.

To do this quick hack, the most common two options are:

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

system("pause");

and

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

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

I suggest the latter method, though the first method really triggers on "any" key while the bottom one only triggers on enter.
