CSE 9A  UCSD Fall, 1996
Assignment 1

(Note: All references to Unix directories assume that you
are starting in your home directory in your account
for this courses on icse1, also called sdcc8.)

Required reading: Reichard book Chapters 1, 2, 3 and 
those sections of Chapter 6 that cover the vi editor (or 
if your are using some Unix book other than Reichard 
read the sections on basic Unix and the section on the 
vi editor.) Also, Savitch text Chapter 1.

Programming: Due date (midnight) Thursday October 3, 
1996: Programming Projects 1, 2, and 3 in Chapter 1 of 
the Savitch text (page 33). First do Project 1, then 
modify the program from Project 1 as described in 
Programming Project 2, and finally modify the program 
from Project 2 as described in Programming Project 3. 
(When doing Project 3 be sure to use the program from 
Programming Project 2, not Programming Project 1. Even 
though the texts say you can use either Project 1 or 
Project 2, you cannot; for this assignment you must use 
Project 2 when doing Project 3.) The result of 
Programming Project 3 is the only thing you will turn 
in. You only turn in one program. Programming Projects 1 
and 2 are only steps on the way to Programming Project 
3. You will use the "turnin" program to turn in your 
program. This turnin program will take the file you give 
it and place that file in a directory where we can grade 
it. You can do this at any time on any day before the 
deadline. To turnin in an assignment with the turnin 
program proceed as follows:

Suppose the program you want to turn in is in the file hw1.cxx.

Simply type in the following (while in the same 
directory as the file hw1.cxx):

turnin -c cs9f hw1.cxx

Be sure to use all lowercase letters as shown here. Be 
sure to put spaces where shown. (The number of spaces 
does not matter). To turn in a file with a name 
different from hw1.cxx, simply replace the name hw1.cxx in 
the above example, with the name of the file you want to 
turn in.

Note: 

(1): You will always be turning in a C++ program. You 
should compile it and test it, but when you turn it in, 
you only turn in the C++ program, you do not turn in the 
compiled object code. (We will compile your program and 
run it when we grade it.) 

(2): If you turnin two files (before the deadline), 
only the last one turned in will be used. So, if you 
decide that you did the assignment incorrectly and want 
to redo it, simply redo the assignment and use the 
turnin program again (but before the deadline). 

(3): To learn more about the turnin program, type the 
following at the Unix prompt:

help turnin

IMPORTANT: After you turn in your program for this or 
any other assignment, do not edit it or in any way 
modify the file that contains your homework assignment. 
This will ensure that we can check that you did the 
assignment on time if the turnin program fails. If you 
want to use your program, make another copy of the 
program using the cp command. You safely change this 
second copy.

Your programs will be graded (at least partly) by 
another program. The grading program expects your 
program to behave in certain ways and will reject it 
unless it behaves exactly as expected. Be sure to follow 
the instructions for input and output exactly. 
Otherwise, you will not receive credit for the 
assignment. To see what the input/output behavior of 
your program should be, you can run the object code in 
hw01.o. We have already done this assignment and compiled 
the program. The file hw01.o has the object code produced 
when we compiled our solution. You cannot see the C++ 
code for our solution, but you can run the object code 
and see how your program should behave. The following 
command will copy the file hw01.o to your home directory:

cp ../public/assignments/hw01.o    . 

Do not forget that final dot (period). After you copy 
this file to your directory, you can run the object code 
by typing:

hw01.o 

The compiled version of the program you turn in should 
have the same input/output behavior as hw01.o. (Note: that 
this program is suppose to give an incorrect answer as 
discussed in Programming Project 3; so do not be 
surprised if you get an incorrect answer when you run 
hw01.o.)

We will provide you with object code (like hw01.o) for 
each assignment so that you can see exactly what the 
input/output behaviors of your program should be. 
However, having the right input/output behavior is not 
enough to get full credit. This program and all your 
programs must follow the examples of the programs in the 
Savitch text for style.

This assignment is based on the program in Display 1.8 
of the Savitch text. All the programs in that text are 
in the directory

../public/programs

So you can get a copy of the program in Display 1.8 by 
giving the following command from your home directory at 
the Unix prompt:

cp ../public/programs/ch01-02/01-08.cxx    . 

Do not forget that final dot (period). If you start with 
this file, that will save you some typing, but if you 
are unfamiliar with the text editor, you might want the 
practice of typing in the program yourself.

Assignments 2, 3, etc.

There will be approximately one assignment per week. 
Assignment 2 will be due very soon after Assignment 1, 
so start early. Assignments 2, 3, and so forth will be 
posted in the following directory on the course 
computer:

../public/assignments
