Q2) Discuss rules for naming variables.
Answer: Answers will vary.Variable names must be one word.The name can contain letters,digits,hyphens,underscores,or any other characters you choose,with the exception of spaces.No programming language allows spaces within a variable name.Variable names should have some appropriate meaning.You might think you will remember how you intended to use a cryptic variable name within a program,but several months or years later when a program requires changes,you and your fellow programmers will appreciate clear,descriptive variable names.Some programmers have fun by naming variables after friends or creating puns with the names,but such behavior is unprofessional and marks those programmers as amateurs.
