Answer 1

Answer 2

// c++ example
void func1 () {
cout << "Hello" ;
}
func1 ();
//func1 doesn't return any value, it's just printing hello to the screen.

Void is considered a data type (for organizational purposes), but it is basically a keyword to use as a placeholder where you would put a data type, to represent "no data".
