Overloading Of Constructor In C++ | Constructor Overloading Explained With Real Life Examples

 Overloading Of Constructor In C++ 



What is constructor overloading?

As you know what is a constructor and also what is function overloading. So you know constructors are special class methods which is basically a function which runs at the starting of class always.

So as you know how to overload a function then the constructor is also a function so you can overload a constructor as same as function overloading.


#include <iostream>
using namespace std;


class calculator
{

    public:
    calculator(int a, int b) //constructor with 2 int type parameter
    {
        cout<<"I AM CONSTRUCTOR "<<a+b<<endl;

    }

    calculator(int a, int b, int c) //constructor with 3 int tpe parameter
    {
        cout<<"I AM A OVERLOADED CONSTRUCTOR "<<a+b+c<<endl;
    }

    
};
int main()
{
    calculator c1(1,2);
    calculator c2(1,2,4);
    return 0;
}


Output - 

I AM CONSTRUCTOR 3

I AM A OVERLOADED CONSTRUCTOR 7

So as in this example, the house will call class and the process of building your house will call the  constructor.  So when you create a class or call an object of any class then first before going into class first your class is calling constructor which will run by default but if you want to modify that constructor then you can do it. Constructor is like a simple function that will run every time when we go inside a class. Here is the official definition of a constructor -  A  constructor  is ...

So the same concepts will be applied to objects - A array of objects will be a set of objects. To understand array of objects more clearly suppose you have a form for a job application and you want to send same job application to 100 people. Then rather then creating 100 job application from scratch you can photocopy the same job application form 100 times.Right? So here how you can create array of object in c++ -  #include   < iostream > using   namespace   std ; class   School {      public :        int   std_id ;      int   std_class ;      float   percentage ;      void   add_details ()      {     ...
