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. We are using g++ compiler and terminal to compile the code and ubuntu OS. PROGRAM: #include<iostream> using namespace std; int main() { PROGRAM: int a,b,c; char op,d; do { cout<<"Enter the first number:"; cin>>a; cout<<"Enter the second number:"; cin>>b; cout<<"Enter operator +,-,*,/:"; cin>>op; switch(op) { case'+': ...
