Assignment 6 CISC 220

Bonus Assignment
Assignment 6
CISC 220
Administrative Notes:
This assignment is a bonus assignment. You will not lose marks toward the 100 marks of the
course if you do not do it. Conversely, if you do it correct, you will gain as much as any other
assignment weight in top of what you get out of the 100 total marks of the course marking.
All of the administrative notes from previous assignments apply to this assignment as well. I will
just summarize the main points here and you can refer back to the previous assignments
instructions for more details:
 Your program should work in CASLab Linux servers.
 No group work allowed.
 Hand in your file to OnQ in the “Assignment 6” Dropbox area.
 Follow instructions carefully or you may lose points.
 There is no “grace period” for this assignment as you will be given ten days to finish it.
Deadline:
The deadline for this assignment is Monday, November 26 at 8 a.m.
Required Program:
This is your IO assignment and your task is to write a C program as explained. It can be done
with the features of C we've discussed in the “Input/Output” topic in class. The required program
should be able to read from a text file and breaks the given text into lines on maximum 20
characters.
Each line should hold the maximum number of complete words it could get. The start of the next
line is activated only when the program gets a word that doesn’t fit in the remaining space of the
current line.
For example:
If the given text file contains the following text in one line. A quote from William Shakespeare:
Love all, trust a few, do wrong to none. A fool thinks himself to be wise, but a wise man …
Assume that the maximum number of character a line can hold is 10 then, the sentence will be
broken into the following lines
Char No. 1 2 3 4 5 6 7 8 9 10
Line 1 L o v e a l l ,
Line 2 t r u s t a
Line 3 f e w , d o
Assume that the maximum number of character a line can hold is 15 then, the sentence will be
broken into the following lines
Char No. 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15
Line 1 L o v e a l l , t r u s t
Line 2 a f e w , d o w r o n g
Line 3 t o n o n e a f o o l
The program output doesn’t have to be included in boxes like this. They are used just for demo
purposes. For testing, different testing text files will be used. The testing text file will contain
only one line that is very long with only one end of file and one EOF.
You function should be based on the following function that we covered in class:
Char* fgets (char *s, int count, FILE *stream)
Copy of this function developed for demonstration purposes by Dr. Lamb is available at the
following Linux directory:
cas/course/cisc220/IO/IOtest5.c
You may use the IOtest5 in your program and improve on it so it will not split a word into two
parts. Or you may develop your own similar function, which is better.
Same concepts that are used in IOtest5.c should be used in your function.
If your function works properly with different set of text files and different lengths of lines, then
it will be given full mark.
More Requirements:
Your program must be in a single file called CISC220-Assn6.XXXX.c
the XXXX represent your last four digits of your students ID.
Marking Scheme:
If you use pointers in your functions, and if your function works properly with different set of
text files and different lengths of lines, then it will be given full mark of 20 marks.
If you do not follow the assignment requirements -- especially if you deviate from them in a way
that costs us time while marking -- you will lose administrative points even if your program
works correctly. So please read the directions carefully.
