Assignment 5 Class For Basic Complex Number Operations 1. A complex number is of the form a + ib. Let x = a +ib and y = c +id. The operation of adding two complex numbers is: x + y = (a + c)+i(b+d). The operation of subtracting two complex number is: x-y = (a -c)+i(b-d). The operation of multiplying two complex number is: xxy = (ac - bd) +i(bc + ad). The operation of dividing two complex number is:...
A complex number is a number in the form of a + bi, where a and b are real numbers and i is the square root of negative 1. Design and create a class called Complex for representing complex numbers. This class should have two attributes, a and b, which represent the parts of the complex number. This class should overload the +,-,*,/,++ and -- operators (both prefix and suffix) to perform basic complex number calculations according to the following...

A complex number is a number in the form a + bi, where a and b
are real numbers and i is sqrt( -1). The numbers a and b are known
as the real part and imaginary part of the complex number,
respectively.
You can perform addition, subtraction, multiplication, and division
for complex numbers using the following formulas:
a + bi + c + di = (a + c) + (b + d)i
a + bi - (c + di)...
