Question

I’ve set up a compiler /Za option to disable lanquage extensions so that compiler uses strictly standard ISO C++.
Here is sample interface class for which I’m receiving following warning

warning C4180: qualifier applied to function type has no meaning;
ignored

It is about const qualifier in return type of function, if I remove const, warning disapears but I don’t wanna do that, neather I want to enable lanqage extenstions back.

My question is is: Is that warning reasonable?
If it is not then I’ll use pragma to disable the warning but before that I would like to be sure that this warning is “false positive”

Because The following class is Correct ANSI ISO C++ Isn’it? so the warning should be disabled?

    class IBet
    {
    public:
        IBet() { };
        virtual ~IBet() = 0 { };
        virtual const float parentChips() const = 0; // Warning C4180
        virtual const short parentChilds() const = 0; // Warning C4180
            // ...
    };

Answer 1

The return value of the two functions is declared as const. Since it is passed by value it has no meaning. You can remove that const since it serves absolutely no purpose.
