Supplementary Notes

1. Keywords are reserved words. They have a special pre-defined meaning to the compiler. We cannot use them as variable names, function names, etc.
2. ‘do’ is a keyword, ‘while’ is a keyword. ‘do while’ is not a keyword.
3. ‘else’ is a keyword, ‘if’ is a keyword. However, ‘else if’ is not a keyword. Similarly, ‘elseif’ is not a keyword.
