Question

Mention the rules for naming variables

Answer 1

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.
