Complex numbers are numbers that contain two components:a real part and an imaginary part. If a is the real component and b is the imaginary component, this notation is used to represent the number: a + b i Write an Objective-C program that defines a new class called Complex. Following the paradigm established for the Fraction class, define the following methods for your new class: -(void) setReal: (double) a; -(void) setImaginary: (double) b; -(void) print; // display as a + bi -(double) real; -(double) imaginary; Write a test program to test your new class and methods.
