    calling a method in a composite class .

    I have a class A that has a private member variable ab.I also have a method that works with my variable ab.I have another class b that has class A a as a member variable(composition).I have discovered that if i try to call a method from class a it does not work.e.g this.a.getME().I am from a java background and it would work perfectly in java

    That sounds weird ... did you make the getME() function public in A?

    Did you #include the header file for class A? (I think that's different from Java.)

    this.a.getME()
    'this' is a pointer in C++, use the '->' operator.

    And if that does not work, then show us some code.

    Outside of your DOS world, your header file is meaningless.
