Programming Assignment 2 -- DUE 10/26/01 5:00pm

Write a program that will take compute the sum, difference, product of two complex numbers.  The user input will be kept simple and will prompt for each corresponding coefficient.  The format of the complex numbers is shown here.

Complex number 1: r1 + (c1)j
Complex number 2: r2 + (c2)j

Example output is shown below:

Enter r1:  1
Enter c1:  1
Enter r2:  1
Enter c2:  2

(1+1j) + (1+2j) = (2 + 3j)
(1+1j) - (1+2j) = (0 + -1j)
(1+1j) * (1+2j) = (-1 + 3j)

Use input.s for your I/O
Since input.s only reads in positive integers, you will only be required to accept positive integers as input
