Constructor Overloading When more than one constructor function is defined in a class, then it is called constructor overloading or the use of multiple  constructors  in a class. It is used to increase the flexibility of a class by having a greater number of constructors for a single class. Overloading constructors in C++ programming gives us more than one way to initialize objects in a class.
