Hello Hiteshwar, Before answering copy constructor, I will like to discuss a bit more before it. While we are creating an object, the constructor calls to initialize and build that object. If one object already exists for which constructor would be called to create it. Now we want the same object to be copied to another object. So we are creating a new object, and during declaration, we are assigning it to an existing object. Here the new object is creating, So definitely constructor will be called, but which constructor? So to copy the current object to the newly created object C++ lang feature added another particular constructor which is nothing but copy constructor. Hope it's clear to you. If any query, let us know!!! read less
