Balloon sort program in c

#include <stdio.h>

int main()

{

    int num, N[10], x, y, z, temp;

    printf("How many number would you like to sort : ");

    scanf("%d", &num);

    printf("Input the %d numbers :\n", num);

    for (x = 0; x < num; x++)

        scanf("%d", &N[x]);

    for (x = 0; x < num; x++)

    {

        for (y = 0; y < num - x; y++)

        {

            if (N[x] > N[x + y])

            {

                temp = N[x];

                N[x] = N[x + y];

                N[x + y] = temp;

            }

        }

        printf("step %d : ", x + 1);

        for (z = 0; z < num; z++)

        {

            printf("%3d", N[z]);

        }

        printf("\n");

    }

}
