Hi Mustafa,
> Why CV qualifier cannot distinguish two functions for overloading ?
The const is an implementation detail. It is not distinguishing for pass-by-value.
You can do this:
// Header
extern void Foo(int);
// Source implementation
void Foo(int const inValue)
{
// ...
}
And that Foo will have the correct name mangling to implement the declaration in the header.
That is NOT the situation for pass-by-reference or pass-by-pointer.
These two are different:
extern void Foo(int*);
extern void Foo(int const*);
While the pointer itself (which is pass-by-value (i.e., the pointer value)... ugh, don't think about it too hard or you'll hurt your brain) cannot use const to distinguish:
extern void Foo(int*);
extern void Foo(int* const); // Not a distinguishing overload.
