C++ Question

is it a good style to compare strings this way?

I have this in mind to use in a


bool operator==(char const* const a, char const* const b) noexcept
return !::std::strcmp(a, b);

Is this good style?


I think the tasteful c++1z way, that accomplishes the same thing, would be to use the new
class for comparisons.

You can't overload operator which doesn't take class or enum as its operands, which means you can't change the behavior they work with build-in types.

When an operator appears in an expression, and at least one of its operands has a class type or an enumeration type, then overload resolution is used to determine the user-defined function to be called among all the functions whose signatures match the following:

I'll suggest you to use std::string intead of char*, which provide operator==. Then you can avoid using of std::strcmp(), and such kind of c-style string functions at all. If you do need a c-style string, you can use std::basic_string::c_str() to convert it back when necessary.
