Understanding _tmain in Visual C++ console projects

Question

In Visual C++ 2008 Express, when I create a new console project I get the following program to start with:

//Explodey.cpp : Defines the entry point for the console application.

//

#include "stdafx.h"

int _tmain(int argc,_TCHAR* argv[])
{
  return 0;
}

I have a few questions about it:

• Why is the main function _tmain instead of main?

• I'd thought the argv parameter was supposed to be char* argv[] instead of _TCHAR.

• What's stdafx.h?

This doesn't really feel like the same C++ I'm used to.

Answer 1

Take a look here for _tmain... etc.

What is the difference between _tmain() and main() in C++?

stdafx.h is a precompiled header (optional) for Windows applications. More here:
