ALGORITHM:

Step 1: Start the program.
Step 2: Declare the class.
Step 3: Declare the variables and its member function.
Step 4: Using the function getvalue() to get the two numbers.
Step 5: Define the function operator ++ to increment the values
Step 6: Define the function operator – -to decrement the values.
Step 7: Define the display function.
Step 8: Declare the class object.
Step 9: Call the function getvalue
Step 10: Call the function operator ++() by incrementing the class object and call the function display.
Step 11: Call the function operator – -() by decrementing the class object and call the function display.
Step 12: Stop the program.

PROGRAM:

#include<iostream.h> #include<conio.h> class complex {      int a,b,c;     public:           complex(){}           void getvalue()          {                    cout<<"Enter the Two Numbers:";                    cin>>a>>b;          }     void operator++()         {                    a=++a;                    b=++b;          }          void operator--()          {                    a=--a;                    b=--b;           }           void display()           {                    cout<<a<<"+\t"<<b<<"i"<<endl;            }   };   void main()   {        clrscr();        complex obj;        obj.getvalue();        obj++;        cout<<"Increment Complex Number\n";        obj.display();        obj--;        cout<<"Decrement Complex Number\n";        obj.display();        getch();   }

Output:

Enter the two numbers: 3 6
Increment Complex Number
4 + 7i
Decrement Complex Number
3 + 6i
