Design a class Increment for handling Complex numbers and include the following:

_ real: a double

_ imaginary: a double

The class has the following member functions.

a. A constructor initializing the number with default parameters.

b. Getters and Setters of the class data members as given below

_ void setReal(double r)

_ double getReal()const

_ void setImaginary(double i)

_ double getImaginary() const

d. Overload unary ! operator which returns true if the real and the imaginary parts are zero,

otherwise return false.

bool opeator!()const

rite main function to test all the implemented functionality.
