I just started coding c# 4 days ago. I just finsihed my first ever Console Program. I would like to hear some suggestions, on how I could improve my code. I would also like to add that this is my first programming language, so I'm still very new to coding.
Also, the namespace says FourFunctionCalcProgram, but the calculator can dore more than 4 things. I just don't know how to change it.
using System;
using System.Threading.Tasks;

using System.Diagnostics;
using System.Runtime.InteropServices.ComTypes;
