Compiler Design Programs

1. Design and implement a lexical analyzer using C language to recognize all valid tokens in the input program. The lexical analyzer should ignore redundant spaces, tabs and newlines. It should also ignore comments. Link

2. LEX Programs
   - LEX Program to count the numbers of lines, words, spaces, and characters in a given statement Link
   - LEX Program to convert the substring abc to ABC from the given input string.Link
   - LEX program to find out total number of vowels and consonants from the given input sting.Link
   

3. YACC Programs
   - Generate a YACC specification to recognize a valid arithmetic expression that uses operators +, – , *,/ and parenthesis. Link
   - Generate a YACC specification to recognize a valid identifier which starts with a letter followed by any number of letters or digits. Link
   - Implementation of Calculator using LEX and YACC. Link
