CS201 - Information

1. CS201 - Information

2. CS201 - Laboratories • All labs will be done using Linux on the PC’s or esus. • All labs MUST use Makefiles. • First lab is due NEXT WEEK at the end of your respective lab period. • You will need to learn a Linux based text editor, such as pico, vim, or emacs.

3. CS201 – Help Sessions • With a few exceptions (e.g. 2/18), there will be a help session on Fridays in ROBH101 at 3:10 p.m. • This session will cover auxiliary material related to lecture and labs. For example, the first help session (1/14) will be on Linux, using a text editor, and compiling and running C programs

4. CS201 - Suggestions • Do the reading assignments BEFORE coming to lecture. • Take advantage of the exercises and self-tests in the text. • Review the lab assignments, design your solution, and do some preliminary coding BEFORE your lab period.

5. CS201 – esus accounts • You will need to have an esus account to login to Linux on the machines in EPS254. • Wait until you get your esus account to do lab #1. (No late penalties on this lab only).

6. CS201 - Enrichment • These are things that are not on the direct path of CS201 material but would be useful and interesting to advanced students. • No exam questions will be directly on enrichment topics. • C puzzles, additional lab procedures, or C++ related topics.

7. CS201 – Lab #1 – (1/18-1/19) • Boot the machine into Linux. • Login to the machine. • Use a text editor to build the “hello world” program. • Use a text editor to build a simple Makefile for the “hello world” program. • Using the Makefile, compile your program and run it. • Print out the Makefile and your source code file.

8. “hello world” C program /* helloworld.c * CS201 – S’05 – by (your name here) */ #include <stdio.h> int main(void) { printf(“Hello World!\n”); exit(0); }

9. helloworld Makefile # Makefile for helloworld # CS201 – S’05 by (your name here) helloworld: helloworld.o gcc –o helloworld helloworld.o helloworld.o: helloworld.c gcc –c helloworld.c

10. CS201 – sample make $ make gcc –c helloworld.c gcc –o helloworld helloworld.o $

11. CS201 – Sample run $ helloworld Hello World! $

12. CS201 – lab #1 enrichment • Try changing the helloworld program so it says “Happy New Year!” instead of “Hello World!”. • Try printing a line of astericks *************** before and after the “Happy New Year” message. • If you wanted to use the C++ compiler instead, replace gcc with g++.
