std::min gives error

#include <algorithm>
#include <Windows.h>

int main()
{
int k = std::min(3, 4);
return 0;
}


What is windows doing, if I include Windows.h I cant use std::min in visual studio 2005. The error message is:

error C2589: '(' : illegal token on right side of '::'
error C2059: syntax error : '::'

Answer

The windows.h header file (or more correctly, windef.h that it includes in turn) has macros for min and max which are interfering.

You should #define NOMINMAX before including it.
