Program to Add Two Complex Numbers

Given two complex numbers of the form a_{1} + ib_{1} and a_{2} + ib_{2}, the task is to add these two Complex Numbers.

Here the values of real and imaginary numbers is passed while calling the parametrised constructor and with the help of default(empty) constructor, the function addComp is called to get the addition of complex numbers.

Example:

Input: a1 = 4, b1 = 8
        a2 = 5, b2 = 7
Output: Sum = 9 + i15
Explanation:
(4 + i8) + (5 + i7)
= (4 + 5) + i(8 + 7) 
= 9 + i15

Input: a1 = 9, b1 = 3
        a2 = 6, b2 = 1
Output: Sum = 15 + i4

The following program is the illustration of the above example

Output:


Complex number 1 : 3 + i2
Complex number 2 : 9 + i5
Sum of complex number : 12 + i7
