Write A C++ Program To Depict Initialization Of Object Using Default Constructor Without Default Arguments.

#include<iostream.h>


#include<conio.h>


class rec


{


      private:


                      int I,b;


      public:


                      rec()


                 {


                      I=4;


                      b=3;


                 }


                      int area()


                {


                      return(I*b);


                }


};


    void main()


{


    clrscr();


    rec obj;


    cout<<"Area is : "<<obj.area();


    getch();
