Container to pointers of inherited objects

[axel22]

Hello.
Please take a look at this piece of code:


class baseC {
//...
};

class derivedC : baseC {
//...
};


int main() {
baseC b1;
derivedC d1;
std::vector<baseC*> vex;

vex.push_back(&b1);
vex.push_back(&d1);


return 1;
}

Compiler returns an error on the second push_back - type cast:
conversion from 'derivedC * __w64' to 'baseC * const' exists, but is
inaccessible.
Can anyone tell me how to do this without the explicit cast, such as
(baseC *)(&d1);

thnx.

What do you know, it works. I thought public inheritance was the
default inheritance.

Thnx a lot!

It is default for struct, but not for class.
