Suppose I have a method1 in the parent class and I want to override it in a subclass. Does adding const affect the overriding? For example,

int Subclass::method1(const int a)const {...}

Does this override

int Parentclass::method1(int a) {...}

correctly?

I would expect it not to compile – Alexey S. Larionov Jan 28 '21 at 20:55

In modern C++ you can add the `override` keyword when you experiment so the compiler can warn you if the function doesn't override. – user4581301 Jan 28 '21 at 20:58
The originally listed duplicates are wrong, because they involve member function constness and this question asks about top-level const on a function argument. – Ben Voigt Jan 28 '21 at 21:15
Luckily I can add a more relevant function to the duplication list. – Ben Voigt Jan 28 '21 at 21:17
The `const` for a method changes the signature. The two methods are different because of both the `const`. – Thomas Matthews Jan 28 '21 at 22:04
