6.2 Grammars 6.3 Lexical analysis 6.4 Tokens 6.5 Pre-processing directives 6.1 ProgramsA C# program consists of one or more source files, known formally as compilation units (§14.2). Although a compilation unit might have a one-to-one correspondence with a file in a file system, suc...
A program which performs lexical analysis is termed as a lexical analyzer (lexer), tokenizer or scanner. There are three approaches to building a lexical analyzer: 1.Write a formal description of the tokens and use a software tool that constructs a table-driven lexical analyzer from such a...
