Variable Naming Rules

Introduction
This paper will describe the variable naming rules of three different programming languages. These three languages are Visual Basic, Python, and Java. Each of these languages has different rules that apply to them and some similarities. I will describe the rules and the similarities and differences in the next few paragraphs.
Key Findings
The first language and its rules I will describe is Visual Basic. Visual Basic has a few different rules and they are described on Microsoft’s website in a document. This document is called (“Visual Basic Naming Rules”) and they read as such:
You must use a letter as the first character.
You can 't use a space, period (.), exclamation mark (!), or the characters @, &, $, # in the name.
Name can 't exceed 255 characters in length.
Generally, you shouldn 't use any names that are the same as the functions, statements, and
Some similarities in these programs are that there are specific words you cannot use in each language. These words are generally reserved for some other part of the language and if the is not some kind of distinction between the words this will cause an error. Though these languages have minor similarities they differ in the same way, some are case sensitive while others are not. They also say that most variables should begin with a letter but in two of these programs they can begin with an underscore and in Java you can use a dollar sign as well. Another key difference is the length of the variable name, in Visual Basic you are limited to a length of 255 characters while the other two have no restrictions on length. So for each language there are minor similarities and differences but in order to program in any of these languages you must know these rules in order to prevent errors from
