麻烦看看这个程序为什么不能选择排序

Question

#include
int main(void){
int n,a[10],i,j,t,index;

printf("Input n: ");
scanf("%d",&n);

for(i=0;i<n;i++)
    scanf("%d",&a[i]);
    for (i=0;i<n;i++){
        index=i;
        for(j=1;j<n;j++){
            if (a[j]<a[index])
                index=j;
                a[index]=t;
                a[index]=a[i];
                a[i]=t;}}

                printf("After:");
                for (i=0;i<n;i++)

                printf("%d",&a[i]);
                return 0 ;}

代码应该为以下

 #include
int main(void)
{
    int n,a[10],i,j,t,index;
    printf("Input n: ");
    scanf("%d",&n);

    for(i=0;i<n;i++)
        scanf("%d",&a[i]);

    for (i=0;i<n;i++)
    {
        index=i;
        for(j=1;j<n;j++){
            if (a[j]<a[index])
            {
                index=j;
                a[index]=t;
                a[index]=a[i];
                a[i]=t;
            }
        }
    }

    printf("After:");
    for (i=0;i<n;i++)
    printf("%d",&a[i]);
    return 0 ;
}
