Answer 3

If you're asking about functions being defined outside of the main function, then yes, this possible. You can also declare the function above main using a function prototype and then define the function below main as well.

int twoTimes(int n);
int main() {
cout << twoTimes(4) << endl;
return 0;
}

int twoTimes(int n) {
return 2 * n;
}
