Rules for naming variables in C++ : A variable name should be start with an alphabet or a underscore "_". A variable name can have alphabets "a to z", "A to Z", numbers "0 to 9" and an underscore "_". examples: a a1 _a _1 _a1 a_1 a_11 a13 a16_ _3a abc _abc _ab45 ab45 all of these are correct.

not compulsory at all.. make sure you use identifiers that you remember easily cuz identifiers improves the code readability char fn[10] char ln[10] these aren't the good method of declaring instead use full name char first_name[10] char last_name[10] and avoid special characters.
