Look at this program: int main() { int x = 4; displayMessage(); return 0; } void displayMessage() { for(int x = 1; x <= 100; x++) cout << "I love computer science" << endl; } What will the output be? Answers: Nothing. It won't compile because you can't define the variable x inside a loop heading. Nothing. It won't compile because the displayMessage function is being called before it has been defined "I love computer science" 100 times "I love computer science" Nothing. It won't compile because you can't call a void metho
