How to write hello world without modifying main function? Thanks

int main(){return 0;}

Answer 1

Just add this code to a .cpp file somewhere.

class Hack {
  Hack() { cout << "Hello World"; }
} hackInstance;

Answer 2

Use the preprocessor to #define an expansion for return to print hello world, then return.

Answer 3

I'm assuming there's a creative use of #define preprocessor statements that can make this work.

Answer 4

#include<iostream>

int hello() {
    cout<<"Hello World"<<endl;
}

static int foo = hello();

int main(){return 0;}

Answer 5

Yes, strange.
