C++: Initialization of inherited field

Question

I\'ve a question about initialization of inherited members in constructor of derived class. Example code:

class A
    {
public:
    int m_int;
    };

class          


        

Answer 1

What you want is this:

class A{
public:
    A() : m_int(0);
    int m_int;
};

so that m_int is initialized in the correct place.

Edit:

From a comment above, the reason the compiler complains when you try to initialize the m_int variable in B is that it's already been initialized by the constructor of A. That is, you can't re-initialize something, only reassign. So, you can reassign like Ben Jackson stated above or you can initialize in the proper place.
