Description: Compiler theory lexical analysis experiment
First, the purpose of the experiment :
Design prepared by commissioning a specific lexical analysis program to deepen the understanding of the principles of lexical analysis . And mastery of the programming language source code scanning process will be broken down into various types of word lexical analysis methods .
Second, experimental content
Preparation of an ability to analyze integer, decimal , string, identifier , separator, lexical analysis program operators and keywords. At the same time to be able to filter line comments and block comments.
Third, the experimental requirements
