Re: copy constructor not being called

This line calls base(const char) constructor and that is the correct
behaviour. This sytanx means that object b1 is initialized with
value 'x'. It's equivalent to:

base b1('x');

BTW. The same two methods of initialization can also be used for
build-in type:

int i = 1;
int j(2);

What you say is true, but for an assignment operator. For example:

base b;
b = 'x'; // tem****ary base object created from 'x' and copied into b
