This forum is full of questions (and answers) regarding this issue, just search for 'EOF'.

e.g.:

in problem named coins how to stop taking inputs

my code

#include
int main ()
{
int n;
while(scanf("%d", &n) != EOF) {
int sum = (n/2) + (n/3) + (n/4);
if ( sum >= n ) {
printf("%d\n",sum);
}
else {
printf("%d\n", n);
}
}

return 0;
}
