CS 2022 Fall 2009 Assignment 2 9 14 2009 Due Friday 9 18 2009 11 59 PM In this assignment you are asked to write a small C program to demonstrate command of principles we have discussed in class so far Characters Frequency Calculator You are asked to write a C program charfreq c that will take in multiple command line arguments and output statistical information about these arguments More specifically your program will output a table listing all the characters letters numbers spaces or whatever i e you do not have to check if the contents of the passed in strings are alphabet letters Here are some example runs charfreq HELLO CLASS H 1 E 1 L 3 O 1 1 C 1 A 1 S 2 charfreq i can count 123 i 1 c 2 a 1 n 2 o 1 u 1 t 1 1 1 2 1 3 1 Notice that each character is printed in the table exactly once Also notice that the space character was printed in the first example but not the second because the first example had only one command line argument which happened to contain the space that is why the quotes were used while in the second example three separate command line arguments were passed in and no spaces were in any of them The characters must be printed in the order as they appear in the arguments list Technicalities In this assignment you have to demonstrate your knowledge of complex C types So you must store each character count in a instance of a struct you define and you have to link structs to one another via pointers So for example you should define and use something like this struct char count char c int count struct char count next Of course you may use typedef to make dealing with that struct a bit less wordy ugly The next pointer points to the next character count and the pointer in the last struct instance should point to NULL Thus printing out the table should just be a matter of starting at the first struct printing that character and its its count then going down to the next character count struct Submission and Testing Submit your work on CMS http cms csuglab cornell edu by the deadline Make sure you have been added to CMS early on and otherwise contact me via email You should submit the source code the c files of your application and not the compiled binaries Your programs will be compiled with gcc and tested on a linux environment You are free to choose the environment of your liking to develop your solutions but keep in mind that testing will be on a fixed environment and your application is expected to run on that Academic Integrity Reminder Remember that you may have general discussions about how to approach this problem with your peers but you should work on the final solution by yourself alone If you are stuck or are having trouble you may email me or talk to me after class on Monday or during my office hour on Wednesday Good Luck
