Lexical Analyzer in C For the lexical analyzer, you will be provided with a description of the lexical syntax of the language. You will produce a lexical analysis function and a program to test it.

Due Dates Checkpoint (10%): Parts 1-3, Due Tuesday Feb. 9 before at thebeginning of class(you may not use a late day on the checkpoint)Complete Project (90%): Parts 1-4, Due: Tuesday Feb. 17BEFORE 2 am (late Monday night)You should submit a hard-copy of the checkpoint to me (stapled andwith your names on it).You should submit parts 1-3 when you submit part 4. You can do soelectronically (in ASCII, postscript or pdf) with the part 4 files youtar up and submit via cs75handin, or you can give me a hard copy of yoursolution to parts 1-3 (if you changed it since the checkpoint,you should submit your new version of parts 1-3). Project Part 1 FAQ I'll post answers to questions I get about this assignment here:.

  1. Easy Tutor author of Program to implement Lexical Analyzer is from United States.Easy Tutor says. Hello Friends, I am Free Lance Tutor, who helped student in completing their homework. I have 4 Years of hands on experience on helping student in completing their homework. I also guide them in doing their final year projects.
  2. Oct 12, 2017 - Learn how to write a program to implement lexical analyzer in C programming with an example and explanation.

lexemes: it is okay to assume that there is some max size of lexemesin your program (use a #define and set it to something large like 256 orlarger). You can then use a statically declared array for storing a token'slexeme. Gcc, of course, would not do this and would support lexemes ofany length by dynamically allocating a large enough array to store it, butfor your compiler it is fine to assume that you will not encounterprograms with identifiers of more than 256 characters. To get the value of integer and character literals from a C- program:atoi converts a C string of digit characters to an integer. What to Hand in For Parts 1-3A hardcopy of a report containing the following should be submitted to mein class:.

A list of token types from part 1. The regular expressions form part 2. A drawing of your DFA from part 3You are welcome to turn in a hand written solution or you can use someword processing software. In Unix, you can use xfig to draw figures,and then export them as postscript files that can be imported into alatex document.

A Note on Code Style and Grading:Correctness counts for only part of your grade. To receive an A, yoursolution must be correct, robust, and efficient, have good modular design,and be well commented. I am picky well commented code, and I suggest youread my section about commenting C code.My general advice about commenting is to write the comment first,then write the code. This way your comment will help guide your codewriting.

Also, by writing the comment at the same time as the code,your comments and code are more likely to match, andit is more efficient (you do not have to go back laterand try to figure out what a function does so thatyou can write its comment).In addition, code you write should be easily extensible to allow for largerproblem sizes. For example, if you use a fixed-sized char array to storethe lexeme of the current token, then use a constant to define the sizeof this array (e.g. #define MAXLEXEME 512) and use theconstant rather than its value in your code (e.g.x = MAXLEXEME; rather than x = 512;).This way, your program can be easily modifiedto handle a larger max lexeme size by making just onechange to the constant's definition.
