Try this, might not work on your compiler though...

#include <iostream>
using std::cout;

int main() {
cout << __LINE__ << endl;
cout << __LINE__ << endl;
cout << __LINE__ << endl;
cout << __LINE__ << endl;
cout << __LINE__ << endl;
cout << __LINE__ << endl;
cout << __LINE__ << endl;
cout << __LINE__ << endl;
return 0;
}
