In the above example (1) calls copy constructor and (2) calls assignment operator.
What is the main difference between the copy constructor and the assignment operator *?
The Copy constructor and the assignment operators are used to initializing one object to another object. The main difference between them is that the copy constructor creates a separate memory block for the new object. But the assignment operator does not make new memory space.
What is copy constructor explain?

What are the differences between dynamic constructor and copy constructor in C++?
A copy constructor is an overloaded constructor whereas an assignment operator is a bitwise operator. Using copy constructor you can initialize a new object with an already existing object. On the other hand, an assignment operator copies one object to the other object, both of which are already in existence.
