Description: Design a DO-WHILE loop syntax and semantics of lexical analysis programs ﹑, recursive descent parsing options, use the output with a Syntax Directed quaternary intermediate code type. By design, compilation, debugging a DO-WHILE loop syntax and semantic analysis program, syntax and semantic analysis to deepen understanding of the principles and procedures to achieve lexical analysis of the lexical word sequence inspection and analysis.
