#include <iostream>

class World
{
public:
  World() { std::cout << "Hello!\n"; }
  ~World() {std::cout << "Good Bye!\n"; }
};

World TheWorld;

void main() {}

i''m using Dev-C++ 4.9.5.0 to compile the above code but i doesn''t compile at all but by compiling it under VC it works. After i change the void main() {} -> int main(int argc, char *argv[]) {return 0;} it compiles, from what i know, Dev-C++ is the most compliant to C++ compiler in the market, so is it a requirement for us to explicitly code the two parameters in main() to compile the program, does the two parameters a standard of C++?

The problem is the void return of main, it''s not standard.
The standard only allows two forms of "main":

int main(void);

or

int main(int argc, char *argv[]);

Technically the standard allows more forms of main than that, but all forms should have an int return-type.

just do whatever compiles for the main and forgetaboutit, useful command line parameters in games are few and far

Most of the time the IDE writes it for you anyway
