Answer / Sudeep Kumar
A copy constructor is a special member function in C++ used to create a new object by copying an existing one. It's needed because when we use the assignment operator (=) or pass objects as arguments to functions, the original object might get modified, and a copy of the object is required. The copy constructor ensures that a new object is created with the same state as the original.
