error C2614: 'ChildClass' : illegal member initialization: 'var1' is not a base or member

Question

I am getting the following error in C++:

error C2614: \'ChildClass\' : illegal member initialization: \'var1\' is not a base or member

Answer 1

You can't initialize a member of a base class, only of the current class. Use a parameterized constructor in the base class.

Class Base 
{
  protected:
     int var1;
     Base( int var ) : var1(var)
     {}
  public:
     Base()
     {
        var1=0;
     }
};

class Child:public Base
{
      int chld;
   public: 
      Child():Base(0)
      {
         chld=1;
      }
};
