return 0 in function

[BobTheZealotIsEpic]

How do you return 0; in a function?

#include <iostream>

using namespace std;

int a(){
  cout<<"hi";
  return 0;
}

int main(){
  while(true){
    a();
  }
}

This code doesn't stop running. How can I make it stop?

[Smac89]

int main(){
  while(true){
    return a();
  }
}

line 11: How can your loop stop, if the codition never changes?
Maybe you mean this: while( a() );
