1. "assigning" - don't use this word, it should be
initializing an object using another object of same type
2. When the object is passed to function - "by value"
3. when a function returns the object type - "by value"
here doesn't matter if you are assigning that returned
value to to another object or not.

Answer / vikas sood
hi fellows..try this code
class A {
public:
A() { }
A(const A& rhs)
{
cout<<"inside copy constructor..";
}
};
int main()
{
std::vector<A> aVec(10);
}
The answer to this is another reason a copy constructor
will be called.
