Program for Binary Operator Overloading Using C++ Programming

Program to add two complex numbers using binary operator overloading.

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 add two complex numbers.
Step 6: Define the function operator –()to subtract two complex numbers.
Step 7: Define the display function.
Step 8: Declare the class objects obj1,obj2 and result.
Step 9: Call the function getvalue using obj1 and obj2
Step 10: Calculate the value for the object result by calling the function operator + and operator -.
Step 11: Call the display function using obj1 and obj2 and result.
Step 12: Return the values.
Step 13: Stop the program.

}

Enter the value of Complex Numbers a, b: 4             5
Enter the value of Complex Numbers a, b: 2             2

Input Values
4 + 5i
2 + 2i

Result
6 + 7i
2 + 3i
