Using the guidelines in C# coding conventions facilitates the mastery of writing clean, readable, easy to modify, and maintainable code. Use variable names that are descriptive and represent what they are used for, as shown in the following code:
int accountNumber;string firstName;
Also, having more than one statement or declaration on a line clogs readability. Comments should be on a new line and not at the end of the code. You can read more about C# coding conventions at: https://docs.microsoft.com/en-us/dotnet/csharp/programming-guide/inside-a-program/coding-conventions.
