List of Practicals:

• Write a program for finding word, character, line and space count from a given file. 

 

• Write a program to
• Find a keyword in the file and replace it. 
• Remove all the spaces from a file.

 

• Write a program for finding out whether the given equation is well-formed or not. 

 

• Write a program for removing the comments from the given file. 

 

• Write a program to develop lexical analyzer for subset of C language specification. 

 

• Write a program to implement to the lexer that identifies and return tokens and adds them into the symbol table. 

 

• Write a program for recognizing language
• l=a^n b | n>0 
• e.g. : ab, aab, aaab, aaaab, ...
• l=a^n b | n<=5 
• e.g. : VALID : ab, aab, aaab, aaaab, aaaaab 
• INVALID : aaaaaab
• l=a^n b | n is even 
• e.g. : VALID : aab, aaaab, aaaaaab, ... 
• INVALID : aaab, aaaaab, ...
• l=a^n b | n is odd 
• e.g. : VALID : ab, aaab, aaaaab, ... 
• INVALID : aab, aaaab, ...

 

•  Write a program for recognizing language l=a^n b^n | n>0 
• e.g. : ab, aabb, aaabbb, aaaabbbb, ... 

 

• Write a program using LEX and YACC to accept the ambiguous CFG to recognize whether infix expression is valid or not. 

 

• Write a program using LEX and YACC to accept the ambiguous CFG to recognize infix and convert to postfix expression and evaluate it. 

 

• Write a program to generating the various intermediate code forms for a given expression having 
• 3 address code 
• quadruple 

 

• Write a program for generating intermediate code form for a given ‘C’ program having
• conditional statements ( if-else ).
• conditional statements ( while loop ). 

 

• Write a program to given any intermediate code form implement code optimization technique. 

 

• Write a program to generate target code for optimized code.
