Jifeng Chen's 4.2C: Enhanced Functionality for the Calculator Microservice

This is the Jifeng Chen's implementation of SIT323 4.2C

To utilize this demonstration, please follow the steps below:

1. Firstly, initiate the server by executing the following command:

   node server.js

   This command will launch a Node.js process on the server, listening on port 3040.

2. Next, open your preferred web browser and navigate to the following address:
   http://localhost:3040/modulo?n1=10&n2=6
   http://localhost:3040/exponentiation?n1=10&n2=6
   http://localhost:3040/sqrt?n1=10
   

   This action will prompt the server to execute the corresponding arithmetic operation

3. Finally, the server will respond with the answer of the arithmetic operation
