Write A C++ Program To Depict Initialization Of Object Using Default Constructor With Default Arguments.

#include<iostream.h> 
 #include<conio.h> 
 class rec 
 { 
     private: 
     int I,b; 
     public: 
                  rec(int u,int v) 
         { 
                 I=u; 
                 b=v; 
         } 
                int area() 
        { 
                return(I*b ); 
       } 
 }; 
       void main() 
 { 
              clrscr(); 
              rec obj(6,6);       //initialization of object with default arguments 
              rec obj1 (2,8); 
              cout<<"Area is of Rectangle First : "<<obj.area() <<endl; 
              cout<<"Area is of Rectangle Second : "<<obj1.area(); 
              getch(); 
 }
