What are Copy Constructors?

Copy Constructors are constructors used to create the object of a class with another object of the class itself. If a copy constructor is not defined, the compiler generates a copy constructor that does a memeberwise copy of the class. The default copy constructor does a byte to bye copy of the class.

Person q("Mickey"); // constructor is used to build q.
Person r(p);        // copy constructor is used to build r.
Person p = q;       // copy constructor is used to initialize in declaration.
