⚡ Fun fact

My first memorable program, is a Rails chat system that I develop. The fun part is, my friend can communicate with me in his own laptop's browser!

Despite its a simple port forwarding IP, the fact that I can see his chat when I refresh my page, is awesome.

Been loving developing ever since.

🍳 What's cooking?

Delving into Rails for some side project ideas I've been having lately!

🤔 Let's collaborate?

calculator's Issues

Show suitable error message, if validation fails

The software should be able to show an appropriate error message so the user can understand the error from the expressions. Example:

Enter a post-fix expression: 10 *

Error: Invalid expression 10 *

Repeatedly prompt an input

As per requirement 1, the user should be prompted to enter an expression until they entered an empty line(by means of pressing Enter/Return), then the software should quit.

Input validation

The input from the user should be validate.
Developer should be able to check if the input is a String or Float.

Show the expression

The software should be able to show the calculation expression to the user before showing the output, to show that it understands the operation clearly.
