c++ initialized specified for non-virtual method

Question

I have a.h as shown below

class A
{
public:
    void doSomething()=0;
};

Then i have b.h as shown below

#include \"a.h\"

class         


        

Answer 1

The problem is exactly what the compiler says it is.

class A
{
public:
    virtual void doSomething()=0; // virtual keyword needed
};
