- 99 Bottles of Beer on the Wall.
- Current rankings of programming languages.

- CFG tutorial - from the University of Idaho.
In-Class Examples
- plDay1.cpp - checking out C++ scope.
Bash examples
- bash1.sh - first little Bash script.
- bash2.sh - more on evaluation and input
- bash3.sh - still more input and use of files
- bash4.sh - command line arguments
- bash5.sh - FOR and IF statements
- bash6.sh - basic one-dimensional arrays
- bash7.sh - display contents of directory in reverse order using FOR loops
- bash7a.sh - same as above in ONE LINE
- bash8.sh - same as previous, but using WHILE loops
- bash9.sh - Bash trickery
- bash10.sh - displaying words from a file such as data10.txt
Chapter 6 examples
- subtypePoly.cpp - subtypes from base types.
- type.cpp - C++ is, uh, good..?
Scheme solutions
- createList1.scm -
create a list backwards given n:
(makelist 4) --> (4 3 2 1) - createList2.scm -
create a list given n:
(makelist2 4) --> (1 2 3 4) - butLast.scm -
remove the last element of a list:
(butLast '(1 2 3 4)) --> (1 2 3) - palin.scm -
determine if a list is a palindrome:
(palin '(1 2 1)) --> #t - largest.scm -
return the largest value in a list of non-negative integers:
(largest '(1 2 7 5 2 0 3)) --> 7
Chapters 7 & 8 examples
- Makefile - another Makefile example.
- goto.cpp - the infamous GOTO statement.
- break.cpp - a good way to BREAK your code.
- continue.cpp - a way to CONTINUE to break your code.
Chapter 9 examples
- passFunct.cpp - passing a function in C++.
In-Class Examples
Chapter 5 examples
- easyRecur.cpp - basic recursion.
- heapObject.cpp - memory allocation in C++.
- scope0.cpp - example of a static variable.
- scope1.cpp - basic scope in C++.
- staticPascal.p - sample Pascal program.
- dynamicBash.sh - dynamic scoping in Bash.
- fun.py - fun Python scope.
- alias.cpp - finding the sum of squares in a funtastic way... maybe?
- scope.sh - another scope example in Bash.
- scope3.py - another scope example in Python.
C examples
- carlini.c - every CS major can write this program!
- anderson.c. To compile, use -ansi switch, or use this Makefile. (make may have to be installed on csLab machines...)
- CprimerV1.c - all you need to know about C. Well, almost.
- Cprimer.c - final version of Cprimer.c.
- passPointer.c - passing a pointer by value and by reference.
- Ccmdline.c - command line arguments
- readFile.c - how to read a file, such as the file input containing a list of floating point values.
- pointerInClass.c - fun with pointers.
PROLOG examples
- printn.pl - three ways to print 1..n, where n is input.
- power.pl - find X^Y using writes.
- vehicles.pl - tiny database of vehicles (axioms) and a few predicates to query the database. No writes used; just return values.
- leap.pl - leap year problem.
- gcd.pl - finding greatest common divisor using Euclid's algorithm.
