Std::min and Std::max Error resolution

C + + std::min and Std::max such as:

float_t f (float_t x) const {return Std::max (float_t) 0.0, x);}

However, the following code is used:

#include "windows.h"
#include <algorithm>
void foo () {
   int i = 5;
   int j = 7;
   int x = Std::max (i,j);
}

Compiling in VS can cause the following error:

1>test.cpp (7): Error C2589: ' (': illegal token on right side of ':: '

1>test.cpp (7): Error C2143:syntax Error : Missing '; ' Before ':: '

This is because the max and Min macros are also defined in Windows.h, and when you include Windows.h, the program cannot be compiled.

Solution:
1. Windows.h uses a different name, only for Windows systems.

int x = _cpp_max (i,j);
int y = _cpp_min (i,j);

This method changes on the system library and is not recommended.
2. Do not use the Std::max () and Std::min () functions in the system library and replace them with other alternatives such as:

int x = i > J? I:j; Max (i,j)
int y = i < J i:j;//min (i,j)

Simply re-implement these functions, and if you have large amounts of code, you can write a different name function yourself.
3. Add the namespace using namespace Std, or as follows:

Using Std::min;
Using Std::max;
int x = max (i,j);
int y = min (i,j);

This method experiment is not good, I do not know whether I understand wrong, welcome to discuss.
4. Use std::min<int> and std::max<int> as

int x = std::max<int> (i,j);
int y = std::min<int> (i,j);

This method requires prior knowledge of the input data type, but there are problems with different types I and J, such as:

int i = 5;
unsigned int j = 7;
int x = (Std::max) (i,j);
int y = (std::min) (I,J);

The following error occurs:

1>test.cpp (7): Error C2780: ' Const _ty &std::max (const _ty &,const _ty) ':

Summary: Recommended method 2, implement a function of the same function.
