c++ publicly inherited class member cannot be used as default argument

Question

A schematic of my problem...

class A
{
public:
    // etc.
protected:
    uint num;
};

class B : public A
{
public: 
    void foo(uint x = num); //bad
};
         


        

Answer 1

You can use overloading instead of default arguments.

class A
{
public:
    // etc.
protected:
    uint num;
};

class B : public A
{
public: 
    void foo(uint x);
    void foo() { foo( num ); }
};
