Thread: Inheritance question.

I'm wondering about the syntax for inheritance and why I have to use public like this:

Code:

class myClass: public myBase

You don't have to but if you inherit privately or protected you are not able to access the methods of myClass via a pointer to myBase

try this

Code:

class myBase {
public:
    virtual void do_sth() = 0;
    void do_sth_else() {}
};

class myClass: public myBase {
//class myClass: private myBase {
public:
    virtual void do_sth() { do_sth_else(); }    
};


int main() {
    myClass mc;
    mc.do_sth();
    
    myBase * bp = new myClass;
    bp->do_sth();
}

ant try what happens if you change public to private or protected.

Ok, I see, this made it much easier to understand. Thank you both!
