Right way to conditionally initialize a C++ member variable?

Question

I\'m sure this is a really simple question. The following code shows what I\'m trying to do:

class MemberClass {
public:
    MemberClass(int abc){ }
};

clas         


        

Answer 1

Try this:

class MemberClass
{
public:    
   MemberClass(int abc = 0){ }
};

This gives it a default value, and your default constructor.
