找出数组最小值和它的下标

#include<stdio.h>
int main(){
int i,index,n;
int a[10];
printf("Enter n:");
scanf("%d",&n);
printf("Enter %d integers:",n);
for(i=0;i<n;i++){
scanf("%d",&a[i]);
}
index=0;
for(i=1;i<n;i++){
if(a[i]<a[index]) index=i;
}
printf("min is %d\tsub is %d\n",a[index],index);
int temp;
temp=a[index];
a[index]=a[0];
a[0]=temp;
for(i=0;i<n;i++){
printf("%2d",a[i]);
}
return 0;
