Lex Programs:


1. Lex Program to Count the Number of Lines and Characters in the Input File
2. Lex program that implements the Caesar cipher
3. Lex program to find the length of the longest word
4. Lex program that distinguishes keywords, integers, floats, identifiers, operators, and comments
5. Lex program to count the number of identifiers
6. Lex program to count the number of words,small and capital letters, digits and special characters in a C file

8. Lex program to recognize a valid arithmetic expression

Yacc Programs:


1. Program in YACC to evaluate an expression (simple calculator program for addition and subtraction, multiplication, division)
2. Program in YACC to recognize the string „abbb^n, „ab^n „a^n of the langauge (a^n b^n , n>=1)
3. Program in YACC to recognize the language (a^n b , n>=10). (output to say input is valid or not)

    This is an interesting and educational post for students studying business and finance. Corporate finance assignments often involve analysing financial decisions, capital structures, investment opportunities, and business performance. These topics can require considerable research and critical thinking. Students may find corporate finance assignment resources helpful for improving their understanding. Proper academic guidance can support better research, clearer analysis, and more organised assignment writing.
