Homework Grading Criteria
Points for programming assignments are awarded for error-free
compilation, correct program output, and overall program
structure. The program structure grade is an evaluation of the
quality of your code. This includes the following:
- Your code should have a clear, logical organization. Functions
should be written as appropriate to break up the program. Don't put
all of your code in the main function. In general, each function
should easily fit on a single screen and have a clear purpose.
- Variable names and function names should be intuitive and
meaningful. For example, if you need a variable to represent an
employee's salary, use the name salary, not x.
- Use sufficient comments to describe functions and significant
sections of code. These don't have to be long and involved. Keep
them short and clear. Remember, comments are your opportunity to
explain your logic to the TAs. But comments are also a important
piece of documentation for all software, to help future developers
maintain and extend the code.
- Use a consistent, logical method of indentation to make your
program easy to read. For example, code inside a loop or if-else
condition should be indented all at the same level (until reaching the
inside of a nested loop or nested if-else construct).
- Don't type lines of text that are too wide to fit a typical
text screen window (generally no more than 80-90 characters maximum).
Break statements cleanly across multiple lines as needed.
- Avoid the use of global variables. Global constants are
- Follow all instructions for the specific assignment about data
structures required/not allowed, new class declarations, and use/modification of
Use the example code given in class, in lab, and in the textbooks
as guidelines. Programs that are unclear and do not compile will earn
little or no credit.
Program correctness will be determined by evaluating your program on a
series of test data sets. We will make available some but not all of
this data, along with sample output, prior to the assignment due
date. This will help you judge the quality of your program, but will
not guarantee correct results on all data. You will need to ensure
this on your own by creating additional test cases.
