A general rule: You should always name your variable something logical — something that is meaningful within a specific section of code.

Variable Naming Advice:

• Avoid spelling errors. While this can be tricky since you can’t spell check it does actually make a difference.
  • Consider a program with multiple coders and you make a function called euqals instead of equals
  • If the spelling is bad enough you may be violating the “meaningful name” rule!
• Don’t abuse case sensitivity.
  • Don’t create two variables that only differ in capitalization (i.e. ‘one’ and ‘One’). This will get confusing.
  • Don’t create a variable that is a capitalized reserved word.
• Avoid your own abbreviations
  • While you may come up with shorthand that makes sense at the moment it may be something you easily forget
    • If you really want to do this… add a comment explaining what the abbreviation means
  • If someone else is looking at your program this doesn’t follow the “meaningful name” rule
• Avoid swearing
  • It may seem funny or maybe you are venting frustration when debugging… but it is easy to forget you have inappropriate things in your code.
