Examples

Sample 1

Three implementations of functions that compute the fibbonaci sequence.

Demonstrates function calls, looping, and recursion with a well known algorithm.

make && ./fib

Sample 2

An example of reading in structured data from disk.

Useful for teaching cross references, function calls, defining structures, and memory allocation.

Challenges

Challenge 1 - Philadelphia 1776

Features a progressive discovery of:

• Cross references
• Hardcoded password/input
• Loop counting
• Reading from file
• Defining structures
• Complex comparisons
