A constructor is a special member function used to initialize objects of its class. It will be called automatically when the object is created. A class with two or more construct functions with the same name but with different parameters or arguments and other data types is called  Constructor overloading. A copy constructor is a method or member function which initialize an object using another object within the same class. Example: #include <iostream> using namespace std; class ABC { public: int x; // this is parameterized constructor ABC(int a){ x = a; } // this is copy constructor ABC(ABC &i){ x = i.x; } }; int main() { // Calling the parameterized constructor. ABC a1(40); // Calling the copy constructor. ABC a2(a1); cout << a2.x; return 0; }
