10. ENGR 2230 Project Report Format
Note:
The entire document should have 12-point font and single-
spaced, top, bottom, left and right
margins are all 1 inch. All pages should have a page number in
the center at the bottom except
for the title page and appendices.
All headings must be numbered, centered, bolded, and
capitalized at the beginning of the section.
There must be two spaces between the heading and the
paragraph. All subheadings should be
numbered, and left justified and single-spaced.
All figures must have a number and caption underneath, all
tables must have a number and title
above it. There should be one space between the caption and
the figure or the caption and the
table.
Remember this is only a guide of the minimum requirements of
your report. Give me any other
information that you feel is significant and aids the reader in
understanding the purpose,
procedure, and results of your project.

11. Required contents
1. Cover page – including course number and name, assignment
number, date due,
student’s name, professor’s name and your signature. (You must
sign the bottom of
the report on the title page confirming that all work is a product
of your efforts only)
2. Table of Contents (including page number).
3. Problem statement – Write the complete problem statement.
This should give all of
the data and information, specifications for the desired results,
a format, etc.
4. Program description
a. Overview- Describe the strategy (modularity) used to solve
the problem.
b. Variable list – Include a list of names and descriptions of
each input, output
and process variables used in your program listing.
5. Program structure
a. Describe the overall plan (module charts) of how the program
is constructed.
b. Algorithm: List all the major formulas, the theory and
explanations needed in
developing the problem solution algorithm and the computer
program. Use
pseudo codes or flow charts to describe how the program works.

12. 6. A screen shot of Visual C++ window showing the comments
at the beginning of your
program. Must include the first line of your code. If the code is
more than one page,
print the screen shot for the first page only. (MAKE SURE it is
legible. No dark
backgrounds, and make font large)
7. Results – Show screen shots of all the results after executing
your program (if one
screen shot can not show all the results, use several screen
shots).
8. Conclusions – Discussion of the computer program and
results.
9. References – You MUST list all reference materials used
and/or related to the program.
10. Appendix – Computer Program Listing (Print directly from
Visual Studio)
