谢谢各位大神，但是我按照你们的建议改了，还是有点问题，希望你们能继续帮助

#include <stdio.h>
int main()
{
    int temp,x;
    int i,j;
    int a[11]={45,9,63,12,7,3,92,47,9,61};//没必要开那么大数组
    scanf("%d",&x);
    switch(x)
    {
        case 1:
        {
           for(i=0;i<10;i++)
           {
                for(j=9;j>i;j--)
                    if(a[j]<a[j-1])
                    {
                       temp=a[j];
                       a[j]=a[j-1];
                       a[j-1]=temp;
                    }
           }
           for(i=0;i<10;i++)
                 printf("%d ",a[i]);
           printf("\n");
            break;
        }
        case 2:
        {
            for(i=10;i>5;i--)
            {
                a[i]=a[i-1];
            }
            scanf("%d",&a[5]);
            for(i=0;i<=10;i++)
                 printf("%d ",a[i]);
            printf("\n");
            break;
        }
        case 3:
        {
            for(i=3;i<10;i++)
                 a[i-1]=a[i];
            for(i=0;i<9;i++)
                printf("%d ",a[i]);
            printf("\n");
            break;
        }
        
    }
    return 0;
}
这回试试 上次给你改你没说清题意
一定要注意你的书写格式
