Is there 'byte' data type in C++?

Question

If exists is there header file to include?

This code give compilation error:

#include 

using namespace std;

int main()
{
    byte b         


        

Answer 1

namespace std
{
  // define std::byte
  enum class byte : unsigned char {};

};

This if your C++ version does not have std::byte will define a byte type in namespace std. Normally you don't want to add things to std, but in this case it is a standard thing that is missing.

std::byte from the STL does much more operations.
