What does return mean?

Answer 1

I am not sure if its just a bug, but i am seeing that somebody already answered this. But anyway i will post this code, and you will see what is return doing.

#include <iostream>
using namespace std;
int something_else(){
cout << "Something else" << endl;
return 0;
}
int something () {
cout << "This is the second function, which was called by return something() "<< endl;
return something_else();
}
int main() {
cout << "This is main function" << endl;
return something();
}

return is used to return any value..
in case of int datatype mostly we are using return 0
