error: 'INT32_MAX' was not declared in this scope

Question

I\'m getting the error

error: \'INT32_MAX\' was not declared in this scope

But I have already included

#include 

        

Answer 1

 #include  //or 
 #include 

 std::numeric_limits::max();

Note that is a C++11 header and is a C header, included for compatibility with C standard library.

Following code works, since C++11.

#include 
#include 
#include 

struct X 
{ 
    static const std::int32_t i = std::numeric_limits::max(); 
};

int main()
{
    switch(std::numeric_limits::max()) { 
       case std::numeric_limits::max():
           std::cout << "this code works thanks to constexpr\n";
           break;
    }
    return EXIT_SUCCESS;
}
