Const operator in member function (Why can be in two different parts)?

Question

We can find:

1)

const char *get() { return str; }

2)

int get() const { return A; }

What is the differences of "const" in this two different parts of the function?

The first one returns a pointer to const type, and the second is a const function. — Weak to Enuma Elish, Nov 08 '15 at 17:36

The first returns a pointer to a char which is constant - the value of str cannot be modified. This is used to create an unchangable thing.

The second returns an int (from A) which doesn't modify the state of the class - hence can be called when the class is constant.

So in 1) there isn't any prommise of not to modify the parameter (str)? – Pablo De Luca Nov 08 '15 at 20:12
