Lab03, CISC105 Summer 2005

Directions

Write a program for each of the following problems. If you wish, you may start each program using a previous program as a base and then modifying it, BUT you will learn more if you code each one from scratch. Be sure to save every separate program. All programs must be properly commented and indented (see Assignment Standards on the class website).
Some programs below are associated with a question. Answer the question using comments in your code.
During your scripting of the programs, you will compile and run each one. If a program does not compile, don't try to run it (because a.out will not have been created).
Name each program lab02.n.c, where n is the number in the list below. For example, the name of the file for the first will be lab02.1.c

Practicing UNIX

Create a directory for this lab and then go into that directory to create, compile, and execute your programs. Run ls -la

Programs

You should have a total of 11 programs named lab02.1.c to lab02.11.c. Make a single script file (see lab00 for the instructions) where you cat, compile, and run each one in its final form (if it didn't compile, don't run it in the script - mark the place in the printed script file with a marker so it stands out).

Note: Cat, compile, and run each program in order! Do not cat all programs, then compile, etc.

Execute your program multiple times to show that you tested the program well.

More Practicing UNIX

As discussed in class, run ls -la in your lab02 directory. In your printed script file, label the columns for the files' permissions, sizes, dates, and names. Then, label the largest and smallest files and the oldest and newest files. (10 points)

Submission

Email the tar file to Gang by midnight on Wednesday (see lab00 for directions). Give the paper version to Gang at the beginning of your next lab. (15 points for each submission.)

Grading

Grading is as noted above for each program, 10 points for demonstrating your use of UNIX plus 15 points each for the electronic and paper submissions, for a total of 200 points.
