Program to overload a single Unary Operator.

Code :

 #include<iostream.h>  
 #include<conio.h>  
 class optr  
 {  
      public:  
      int a;  
      optr()  
      {  
           a=0;  
      }  
      optr(int x)  
      {  
           a=x;  
      }  
      void show()  
      {  
           cout<<"Addition : "<<a;  
      }  
      optr operator +(optr p)  
      {  
           optr temp;  
           temp.a=p.a+a;  
           return temp;  
      }  
 };  
 void main()  
 {  
      clrscr();  
      int x,y;  
      cout<<"Program will give addition of given two values by overloading unary '+' operator"<<endl;  
      cout<<"Enter Value of X : ";  
      cin>>x;  
      cout<<"Enter Value of Y : ";  
      cin>>y;  
      optr z1(x),z2(y),z3;  
      z3=z1+z2;  
      z3.show();  
      getch();  
 }  

Output :
