In this part you will create a class named Complex to represent complex numbers. (Some languages, including C++, have a complex number library; in this problem, however, you write the complex class yourself.) The members of this class are as follows:

C++

Private data members: real and imag of type double - to represent the complex number (real + imag i)

Private data members: real and imag of type double - to represent the complex number (real + imag i) Public member functions:

Default constructor that will initialize real and imag to zero

void input(istream&); //Input values from the specified stream for real and imag

void output(ostream&); // Output the Complex number to the specified stream in

this form. e.g.,

2.3 + 4.6i

double getReal(); // Accessor method that returns the value of data member real

double getImag(); //Accessor method that returns the value of data member imag

void setReal(double); // Mutator method that sets the value of real

void setImag(double); // Mutator method that sets the value of imag

Write a main() driver function that calls the appropriate member functions to do the following:

Declare two Complex objects: c1 and c2.

Prompt the user and use the input method to input complex values for the two objects c1 and c2. 3

Display c1 and c2 using the output method. Use setReal() to change the value of real for object c2 to 22.2.

Use getReal() to obtain the value of real for object c2; display the value on the terminal screen.

Display the updated c2 value using the output() method.

Example (user input is underlined):

Enter values for real and imaginary coefficients: 17.4 3.9

Enter values for real and imaginary coefficients: 10.2 16.81

17.4 + 3.9i

10.2 + 16.8i

Enter a new value for the real coefficient: 22.2

The new real coefficient is 22.2

22.2 + 16.8i
