CMSC 202 Fall 2001
News and Announcements

24 December 2001
You can obtain the sample input and output files that were used to grade Project 5. They are located on the gl machines under directory:

/afs/umbc.edu/users/b/b/bbenin1/pub/cmsc202/fall01submit/proj5

There are 10 output files (correct.output.1, ..., correct.output.10) corresponding to the 10 cases tested for in the main used for grading, which is in file:
proj5.grader.cpp
in the same directory.
To compare your output with ours, first compile the proj5.grader.cpp file with your source code files (not including any main functions of yours). Then, you can generate output for test case #x by typing:
proj5 x
You can compare the output produced by your program to the correct output in the output files. For the purposes of grading, spacing and the output format of the operator<< was ignored; any other non-trivial discrepancies resulted in a point deduction.

You can obtain the sample input and output files that were used to grade Project 4. They are located on the gl machines under directory:

/afs/umbc.edu/users/b/b/bbenin1/pub/cmsc202/fall01submit/proj4

There are 20 output files (correct.output.1.txt, ..., correct.output.20.txt) corresponding to the first 20 cases tested for in the main used for grading, which is in file:
202.proj4.grader.cpp
in the same directory. There are two sets of output for cases 21-30; those files are named correct.output.bb.n and correct.output.frey.n (where n goes from 21 to 30); each set corresponds to an alternate interpretation of the FixedPoint constructor. Either interpretation was allowed, for students in all sections, as long as it was followed throughout the program.
To compare your output with ours, first compile the proj4.grader.cpp file with your source code files (not including any main functions of yours). Then, you can generate output for test case #x by typing:
proj4 x
You can compare the output produced by your program to the correct output in the output files. For the purposes of grading, spacing was ignored; any other non-trivial discrepancies resulted in a point deduction.

Final Exam Review study guide for sections 0101 - 0104 posted. This is only a guide. There is no guarantee that any of these questions will actually appear on the final exam.
This study guide may be updated from time to time. Follow the link from the course home page.

You can obtain the sample input and output files that were used to grade Project 3. They are located on the gl machines under directory:

/afs/umbc.edu/users/b/b/bbenin1/pub/cmsc202/fall01submit/proj3

There are 16 output files (correct.output1, ..., correct.output16) corresponding to 16 cases tested for in my main, which is in file:
202.proj3.grader.C
To compare your output with mine, first compile my .C file with your source code files (not including any main functions of yours). Then, you can generate output for test case #x by typing:
proj3 x
You can compare the output produced by your program to the correct output in the output files. For the purposes of grading, arrays were allowed to print out with any spacing (one element per line, all on one line, whatever); any other non-trivial discrepancies resulted in a point deduction.
Sections 0101 - 0104
Modifications were made to 202.proj3.grader.C when your projects were graded. The driver program used to test your projects is 202.proj3.dlf.C (also found in /afs/umbc.edu/users/b/b/bbenin1/pub/cmsc202/fall01submit/proj3) which produces less output for each test case than found in the correct.output files. With this one exception, the directions given above for compiling and testing your code still apply. The output that is produced by your program should still match the corresponding output in the correct.output files.

Amit Choudhri will hold alternate office hours on Wednesday, 21 November from 8:30-10am (in the usual location).
18 November 2001
In order to avoid overflow problems, the fractional part of a FixedPoint should be represented as type unsigned long long. (int, long int, and long long int are all not big enough to handle multiplications.)
9 November 2001
The Project 4 description has been modified to clarify function prototypes, printout specifications, and exception throws, along with a few other minor changes. Changes are printed in green.
29 Oct 2001
You can obtain the sample input and output files that were used to grade Project 2. They are located on the gl machines under directory:

/afs/umbc.edu/users/b/b/bbenin1/pub/cmsc202/fall01submit/proj2

There are 5 input files (input1, ..., input5) and 5 corresponding output files (output1, ..., output5). You can compare the output produced by your program on the input files to the correct output in the output files. For the purposes of grading, any prompts to the user were ignored, as were any blank lines printed; any other discrepancies resulted in a point deduction.
17 Oct 2001
The Project 3 description has been modified to specify the behavior of member functions upon encountering errors, and to clarify the memory management scheme.
17 Oct 2001
The project 3 homework description has been modified. Each test case should list the public function(s) it is designed to test
16 Oct 2001
The Project 3 description has been amended to clarify when memory allocation and deallocation should occur.
16 Oct 2001
The deadline for grade changes for Exam 1 and Project 1 has passed; no more requests will be honored.
16 Oct 2001
Final Exam date/time posted on schedule
