Answer 1

修改如下，供参考：

#include <stdio.h>
void  main()
{
    int a[11], i = 0, key, j;
    printf("please enter ten numbers\n");
    for (i = 0; i < 10; i++)
        scanf("%d", &a[i]);
    printf("please enter a number\n");
    scanf("%d", &key);
    for (i = 0; i < 10; i++){
        if (key >= a[9])
        {
            a[10] = key;
            break;
        }
        else{
            if(key < a[i]){
                for (j = 10; j > i; j--)
                    a[j] = a[j - 1];
                a[i] = key;
                break;
            }
        }
    }
    for (i = 0; i < 11; i++)
        printf("%d ", a[i]);
}
