With the following snippet, how many objects of type A are created? I know for sure there is one in line #4, but is there another object of type A created in line #5 as well?
Thanks, lzzzz
-------------------------------
class A {};
class B : public A {};
int main() {
A a = new A(); // line #4
B b = new B(); // line #5
}

Answer Iz,
The easiest way to find the answer is for you to put a print stmt like sprint or AfxMessageBox or whatever will work for your development environment.
Put the print stmt into the class A object constructor method, and you'll see what's happening. This will be more instructive than my just telling you.
