Question

PLEASE WRITE THIS IN C++

Write a ComplexNumber class that has two member variables realNum and complexNum of type double. Your class shall have following member functions

Complex();

Complex(double, double);

Complex add(Complex num1, Complex num2);

Complex subtract(Complex num1, Complex num2);

string printComplexNumber();

Write a driver program to test your code. Please make sure your code is separated into Complex.h Containing definition of the class Complex.cpp Containing the implementation ComplexTestProgram.cpp Containing main program Use the following directive in class definition to prevent duplicate inclusions . #ifndef COMPLEX_H #define COMPLEX_H ... #endif

Your Output should be like

Enter real and imaginary part of first complex number

5

6

Enter real and imaginary part of second complex number

4

9

Sum of two complex numbers is 9+15i

Enter real and imaginary part of first complex number

-7

6

Enter real and imaginary part of second complex number
