Lex program replaces the substring abc by ABC from the given input string
Lex program contains three sections: definitions, rules, and user subroutines. Each section must be separated from the others by a line containing only the delimiter, %%. The format is as follows: definitions %% rules %% user_subroutines In definition section, the variables make up
C program to Design a lexical analyzer for given language and the lexical analyzer should ignore redundant spaces, tabs and new lines
This program reads a C source code file, tokenizes it into keywords, identifiers, and special characters, and counts the lines. It also ignores redundant spaces, tabs, and new lines while processing the input #include <stdio.h>#include <stdlib.h>#include <string.h>#include <ctype.h>void keyword(char str[10]) {// Check if
Convert from NFA to DFA using Thompson’s rule for (a+b)*abb
To convert the regular expression (a + b)*abb from an NFA to a DFA using Thompson’s construction, we will follow these steps: Create an NFA for (a + b)*abb using Thompson’s construction. Convert the NFA into a DFA using the subset construction method.
C Program to Recognize Strings Under ‘a’, ‘ab+’, ‘abb’
This C program is designed to recognize and classify strings according to three specific rules or patterns: a*: A string consisting of zero or more ‘a’ characters. a*b+: A string that starts with zero or more ‘a’ characters followed by one or more
