Describe What Happens During The Lexical Analysis Phase Of Compilation

Describe What Happens During The Lexical Analysis Phase Of Compilation - What is Lexical Analysis? Lexical Analysis is the very first phase in the compiler designing. A Lexer takes the modified source code which is written in the form of sentences . In other words, it helps you to convert a sequence of characters into a sequence of tokens. The lexical analyzer breaks this syntax into a series of tokens. Lexical Tokens A lexical token is a sequence of characters that can be treated as a unit for parsing A language classi es lexical tokens into token types Tokens constructed from alphabetic chars are called reserved words typically can t be used as identi ers E g IF VOID RETURN 6 Type Examples ID foo n14 last NUM 73 0 00

Lexical analysis is the first phase of a compiler. Its job is to turn a raw byte or char-acter input stream coming from the source file into a token stream by chopping the input into pieces and skipping over irrelevant details.

Each token represents one logical piece of the source file – a keyword, the name of a variable, etc. Each token is associated with a lexeme. The actual text of the token: “137,” “int,” etc. Each token may have optional attributes.
