How to use scanf after using while loop scanf !=EOF

I have to input a .in file into my program.gcc ./"file" < file.in
Because there are more than one input I have to use the While loop EOF, but because of that I can't scanf again. Here's a mock version of my program. Thank you

#include <stdio.h>

int main() {
    int arr[100];
    int num;
    int count = 0;
    while( scanf("%d", &arr[count]) != EOF ) {
        count++;
    }
    printf("%d\n", arr[0]);
    scanf("%d", &num);
    printf("%d\n", num);
}

try this

freopen("con:", "r", stdin);//this for windows. "/dev/tty" for *nix ?
scanf("%d", &num);
