What is the difference between wmain and main?

Question

So I have some class starting with

#include 
#include 

and there is a wmain function .

Answer 1

main is the normal program entry point in c & c++ and is passed the command line in single byte characters. wmain is an alternative that is used in many windows programs for unicode programs where it instead gets passed the command line as wide 16 bit unicode characters.

I believe it's a windows extension for unicode programs.
