Accessing protected members in a derived class

Question

I ran into an error yesterday and, while it\'s easy to get around, I wanted to make sure that I\'m understanding C++ right.

I have a base class with a protected memb

Answer 1

Following the hack for stl I wrote a small code which seems to solve the problem of accessing the protected members in derived class

#include 

class B
{
protected:
    int a;
public:
    void dosmth()
    {
        a = 4;
    }

    void print() {std::cout<<"a="<

Prints

a=4
a=5
