Lab Programs (CIE and SEE)

1. Program 1: 
   1. Write a LEX program to count number of words, lines, characters and whitespaces in a given paragraph
   2. Write a YACC program to recognize strings of the form anbn+mcm, n,m>=0.
2. Program 2:
   1. Write a LEX program to count number of Positive and Negative integers and Positive & Negative fractions.
   2. Write a YACC program to validate and evaluate a simple expression involving operators +,- , * and /.
3. Program 3:
   1. Write a LEX program to count the number of comment lines in a C Program. Also eliminate them and copy that program into a separate file.
   2. Write a YACC program to recognize a nested (minimum3levels)FOR loop statement for C language
4. Program 4:
   1. Write a LEX program to recognize and count the number of identifiers, operators and keywords in a given input file.
   2. Write a YACC program to recognize nested IF control statements (C language) and display the number of levels of nesting.
5. Program 5: Write a C program to implement a ShiftReduce parser for a given grammar and generate the parsing table by parsing the given string.
6. Program 6: YACC program that reads the C statements for an input file and converts them in quadruple three address intermediate code.
7. Program 7: Write a YACC program that identifies the Function Definition of C language
8. Program 8: Write a YACC program that generates Assembly language (Target) Code for valid Arithmetic Expression.
