Answer:

Rules for naming variables:

- Variable names in Visual C++ can range from 1 to 255 characters. To make variable names portable to other environments stay within a 1 to 31 character range.

- All variable names must begin with a letter of the alphabet or an underscore ( _ ). For beginning programmers, it may be easier to begin all variable names with a letter of the alphabet.

- After the first initial letter, variable names can also contain letters and numbers. No spaces or special characters, however, are allowed.

- Uppercase characters are distinct from lowercase characters. Using all uppercase letters is used primarily to identify constant variables.

- You cannot use a C++ keyword (reserved word) as a variable name.
