The description mentioned under is not the complete details. just a hint. more details will be shared to selected candidates only Whitespace is defined as any sequence of the blank (space), new line, vertical tab, form feed, and horizontal tab characters. Implementation of continuation of source lines (i.e., the ability to end a line with a backslash character immediately before the end-of-line marker so that it is combined with the next source line as one logical source line) as described in Section 2.1.2 in Harbison & Steele is not a required feature of your compiler. Comments are delimited by /* and */. They are ignored by the lexer and are not returned as tokens. See Section 2.2 in Harbison & Steele: comments are to be replaced by a single space character. A token returned by the lexer is always the longest possible recognizable valid sequence of characters. An identifier is a sequence of letters, digits, and underscores. An identifier must not begin with a digit, and it must not have the same spelling as a reserved word. As stated in Harbison & Steele, Section 2.5, your implementation must permit a minimum of 31 significant characters in identifiers.
