Following the the best practices while declaring a variable.  These best practices maintains code readability, understandability as project code size increases.

  • Variables names should be short or long enough as per the scope. For example, loop counter variable, i is fine whereas employee as loop variable.
  • Specific words should not be used like equals, compare, data.
  • Use meaningful names which can explain the purpose of the variable. For example cnt Vs counter.
