Class method and variable with same name, compile error in C++ not in Java?

Question

class Test {

      bool isVal() const {
          return isVal;
      }

  private:

      bool isVal;
};

On Compiling this file it says

Answer 1

Functions in c/c++ are just pointers to a location in memory where the code is located, isVal (as a boolean) and isVal (as a function) are therefore ambiguous.
