C ONLY PLEASE Write a program that uses functions and structure to perform the following operations:

a. Reading and writing complex number

b. Addition and Multiplication of 2 complex numbers Complex Numbers Ex: 3+2i (real part is 3 and imaginary part is 2) Program must:

Define structure having one real (r) and one imaginary (i) member.

Create two structure variables and read the real and imaginary parts of two complex numbers (e.g. c1, c2).

Compute the sum of complex numbers by adding real part with real and imaginary with imaginary. Store this result in another struct variable. o (c3. R = c1. R + c2. R and c3. I = c1. I + c2. I)

Compute the product of complex numbers and store results into another struct variable, by using the formula: c3. R = (c1. R * c2. R) (c1. I * c2. I) c3. I = (c1. R * c2. I) (c1. I * c2. R) Display the complex numbers. Complex numbers can be visually displayed like this: (r, i).
