Usually when we call an object’s member function, the object is implicitly passed to the member function, despite not being present in the parameter list. P0847 allows us to make this parameter explicit, giving it a name and const/reference qualifiers. For example: struct implicit_style { void

As of C++20, we have four keywords beginning with const. What do they all mean? Are they mostly the same? Let’s compare them in this article. const vs constexpr const, our good old fried from the early days of C++ (and also C), can be applied to objects to indicate immutability. This keyword can also be added to non-static member functions, so those functions can be called on const instances of a
