Expected identifier with numeric_limits

[Food 4 Thought]

I'm trying to perform a simple input operation, and check to make sure that whatever the user input is a valid input (is within data type bounds, is correct data type...). But when I get to ignoring the input, I keep getting an error.

unsigned short num;

while (true)
{
     std::cin >> num;

     if (std::cin.fail())
     {
          num = 1;
          std::cout << "Error" << std::endl;

          std::cin.clear();

          std::cin.ignore(std::numeric_limits<unsigned short>::max/*Error: expected an identifier*/(), '\n');
     }
}

I don't fully understand why this error is here. I'm writing things just as they are on the tutorial.
If someone could help me out, that would be much appreciated.

Microsoft had a bad day and defined lowercase min and max macros in their Windows.h header.

#undef min
#undef max

Or:

#define NOMINMAX

@xismn That's no good in header files as Windows.h will have already been included.

[Duthomhas]

#ifndef NOMINMAX
#define NOMINMAX
#endif
#include <windows.h>

@Duoas

#include <Windows.h>
#include <YourHeader.h> 

What now?

Works like a charm. Thanks guys :)
