Hi,

There is nothing wrong with program might be reason you are not supplying the value to array

for debug purpose you can take an array which have ten element

#include
int main()
{
int arr[10]={1,2,3,4,5,6,7,8,9,10}; // only for testing purpose
int 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;
}
