CS 12, Fall 2008
Assignment 2

Due: Monday, October 27, 9:00pm
Worth: 100 homework points

1. Type answers to the following five Review Questions and five Exercises from Section 2.4 of the Standish text into a plain text file named hw2.txt. Number your answers to correspond with the problem numbers in the textbook.
• Review questions 1, 3, 5, 6, and 7 (i.e., all except 2 and 4) on p. 37; and
• Exercises 1, 2, 3, 5, and 6 (i.e., all except 4) on pp. 37-38.

Before proceeding to step 2: Study the linked list discussion in section 2.5 of the text. Understand the functions that are implemented in that section. Then study the data types and function prototypes in airports.h, the required header file for this project. Save a copy of this file to your working directory (another copy is in ~mikec/cs12/hw2/). Finally study airports.c-skeleton, especially the functions that are already implemented for you.

2. Complete airports.c by following the instructions in the skeleton (also in ~mikec/cs12/hw2/).
   • Write the bodies of each of the six functions. They are all derived from Section 2.5 Exercises 1, 2, 3, 4, 5, and 7, on pp. 53-54 of the Standish text. You should read those text instructions and hints to fully understand the problems to be solved.
   • Test your implementations with hw2.c (in ~mikec/cs12/hw2/ too). One way to compile and link your program (assuming that hw2.c, airports.c, and airports.h are all in the current directory) is to type the following at the Unix prompt:
     
     gcc -Wall -o hw2 hw2.c airports.c
     Be sure that results of executing the program exactly match these part 2 results.
3. Test your programs at CSIL. Then turn them both in at once from your engineering account as follows:
   
   turnin hw2@cs12 hw2.txt airports.c
   Late projects may not be accepted.
