1)Design a class called Complex. The class enables operations on so called complex numbers. These are numbers of the form realPart + imaginaryPart *i, where the i has the value 2)Design the class to have two private members real and imaginary. 3)Provide a default constructor. 4)Provide a copy constructor. 5)Provide set and get member functions. 6)Overload the + operator to enable add of two complex numbers. 7)Overload the == operators to allow comparisons of complex numbers. 8)Enable input and output of complex numbers through the overloaded and << operators. 9)You need to design a class header file, an implementation file and a driver file. The driver file needs to test out each of the member functions completely.
