U4P3

Write a class called “arithmetic” having two integer and one character data members. It performs the operation on its integer members indicated by character member (+, -, *, /). For example * indicates multiplication on data members as d1 * d2. Write a class with all necessary constructors and methods to perform the operation and print the operation performed in format Ans = d1 op d2. Test your class using main().

Code :

 #include<iostream.h>  
 #include<conio.h>  
 class arithmetic  
 {  
      int a,b;  
      char op;  
      public:  
      arithmetic()  
      {  
           cout<<"Give the value of A and B : ";  
           cin>>a>>b;  
           cout<<"\nSelect Operation (+,-,*,/) : ";  
           cin>>op;  
      }  
      void show()  
      {  
           cout<<"\n A "<<op<<" B :== "<<a<<" "<<op<<" "<<b<<" :== ";  
           if(op == '+')  
           {  
                cout<<a+b;  
           }  
           else if(op == '-')  
           {  
                cout<<a-b;  
           }  
           else if(op == '*')  
           {  
                cout<<a*b;  
           }  
           else if(op == '/')  
           {  
                cout<<a/b;  
           }  
           else  
           {  
                cout<<"\nERROR : INVALID CHARACTER";  
           }  
      }  
 };  
 int main()  
 {  
      clrscr();  
      arithmetic obj;  
      obj.show();  
      getch();  
      return 0;  
 }  

Output :
