### Implement a class Complex which represents the Complex Number data type. Implement the following operations: 1. Constructor (including a default constructor which creates the complex number 0+0i). 2. Overloaded operator+ to add two complex numbers. 3. Overloaded operator* to multiply two complex numbers. 4. Overloaded << and >> to print and read Complex Numbers.

Implement a class Complex which represents the Complex Number data type. Implement the following operations:
1. Constructor (including a default constructor which creates the complex number 0+0i).
3. Overloaded operator* to multiply two complex numbers.
