                1.Write a Program for Arithmetic Operator Overloading Program

#include <iostream.h> #include<conio.h> class a {     private:     int data;     public:     void getvalue()     {         cin>>data;     }     a operator+(a ob)     {         a t;         t.data=data + ob.data;         return t;     }     a operator- (a ob)     {     a t;     t.data = data - ob.data;     return t;     } a operator* (a ob)     {     a t;     t.data = data * ob.data;     return t;     } a operator/ (a ob)     {     a t;     t.data = data / ob.data;     return t;     } a operator<(a ob)     {     a t;     t.data = data < ob.data;     return t;     } a operator>(a ob)     {     a t;     t.data = data > ob.data;     return t;     }       int display()     {                 return data;             } }; void  main() {       a obj1, obj2, sum, sub,mul,div,lt,gt;     clrscr();     cout<<"enter an integer value for obj1: ";     obj1.getvalue();     cout<<"Enter an integer value for obj2: ";     obj2.getvalue();     sum= obj1+obj2;     sub=obj1-obj2;     mul=obj1*obj2;     div=obj1/obj2;     lt=obj1<obj2;     gt=obj1>obj2;     cout<<"Addition result is = "<<sum.display()<<endl;     cout<<"Subtraction result is = "<<sub.display()<<endl;     cout<<"Multiplication result is ="<<mul.display()<<endl;     cout<<"Division result is = "<<div.display()<<endl;     cout<<"Less than result is = "<<lt.display()<<endl;     cout<<"greater than result is = "<<gt.display()<<endl;     getch();     }
