what is the problem in this program?

#include <stdio.h>
int main()
{
int arr[10];
int i;
for (i=0;i<10;i++) {
scanf("%d",&arr[i]);
}
for (i=0;i<10;i++) {
int flag = 1;
if (arr[i] == 1) flag = 0;
for (int j=2;j<=arr[i]/j;j++) {
if (arr[i]%j == 0) {
flag = 0;
break;
}
}
if (flag) printf("%d ",arr[i]);
}
return 0;
}

Well,
- You included line numbers where the board will do this for you.
- The code isn't indented.
- You don't actually say what you want it to do, as opposed to what it does do.
- You don't provide an example input which apparently "breaks" the code in some undesirable way.
