Part 1: Fixing a broken program (5 marks)

In the assignment 3 directory (under /home/231/assignments/assignment3) you will find a Pascal program in a Unix text file called "broken.p".  Rename the Unix file to "fixed.p", and change the name of the program (in the header) to "fixed".   Then correct the four syntax errors in the program  so that it will compile.  Aside from making the minimal amount of changes that will allow the program to compile you cannot otherwise change the program (i.e., you can't just simply write your own Pascal program instead of using the one that was provided).

Five marks will be given only for a program that will compile and is properly renamed.  A mark will be lost if the program compiles but is not properly named.   Only one mark will be given for a program that is properly named but does not compile (partial credit for fixing only some of the syntax errors will not be given because it is crucial that you learn early on how to spot and correct syntax errors by interpreting the error messages given by the compiler. 

New concepts to be applied:

Getting familiar with some of the more common syntax errors that prevent program a program from compiling.  The ultimate goal is to be able to produce a program completely free of these errors. 

 

Part 2: Simple text formatting (6 marks)

In the assignment 3 directory (under /home/231/assignments/assignment3) you will find a Pascal program called 'converter.p'.  You are to change this program so that the output matches the output of the executable program called "converter".    What you need to do:

In terms of setting up the text formatting you can assume that the temperatures will only range from -573.3C / -999.9 F to 537.7 C / 999.9 F (Your formatting only has to work for a number with a maximum of three digits for the integer portion of the temperature and one digit for the fractional portion).

New concepts to be applied:

Producing simple formatted output in Pascal.

 

Submission requirements

In addition to having fulfill the generic assignment requirements, the requirements specific to this assignment include:

  1. Include a README file in your submission:  For this assignment your README file must include your contact information: your name, university identification number and UNIX login name so that your marker knows whose assignment that he or she is marking.  Omitting the necessary information from this file will result in the loss of a letter 'step' (assuming that the marker can actually figure out who the assignment belongs to).

  2. Assignments (source code/'dot-p' file and the README file) must be electronically submitted via submit.  In addition a paper print out of the source code and README must be handed into the assignment drop box (located on the second floor of the Math Sciences building) for the tutorial that you are registered in.  Electronically submitting the assignment allows your marker to run the code in order to quickly determine what features were implemented.  Providing a paper printout makes it easier for your marker to read and flip through your source code.

  3. As a reminder, you are not allowed to work in groups for this class.   Copying the work of another student will be regarded as academic misconduct (cheating).  For additional details about what is and is not okay for this class please refer to the following link.
