Constructor Overloading in C++ Improve Improve Like Article Like Save Share Report Prerequisites: Constructors in C++ In C++, We can have more than one constructor in a class with same name, as long as each has a different list of arguments.This concept is known as Constructor Overloading and is quite similar to function overloading. Overloaded constructors essentially have the same name (exact name of the class) and different by number and type of arguments. A constructor is called depending upon the number and type of arguments passed. While creating the object, arguments must be passed to let compiler know, which constructor needs to be called. CPP // C++ program to illustrate // Constructor overloading #include <iostream> using namespace std; class construct { public: float area; // Constructor with no parameters construct() { area = 0; } // Constructor with two parameters construct(int a, int b) { area = a * b; } void disp() { cout<< area<< endl; } }; int main() { // Constructor Overloading // with two different constructors // of class name construct o; construct o2( 10, 20); o.disp(); o2.disp(); return 1; } Output: 0 200 Related Articles : Destructors in C++ quiz on constructors in C++ Output of C++ programs | Set 26 (Constructors) Output of C++ programs | Set 27(Constructors and Destructors) This article is contributed by I.HARISH KUMAR.
