程序是这样的：
#include <stdio.h>
#include <stdlib.h>

int main(void)
{
    int i, n;

    printf("How many numbers do you want to reverse: ");
    scanf("%d", &n);

    int a[n];

    printf("Enter %d numbers: ", n);
    for (i = 0; i < n; i++)
    {
        scanf("%d", &a[i]);
    }
    printf("In reverse order: ");
    for (i = n-1; i>=0; i--)
    {
        printf("%d", a[i]);
    }
    printf("\n");

    system("pause");
    return 0;
}

编译显示：
