Project Information
The project for this quarter applies
data and
establishes report needs for keeping track of your car buying
information. Remember, this lab is just a
starting point
for the quarter long project!
PROBLEM:
Write a program, called lab2.cob using file I/O to output the
input
information in report format. The
input
file, which will not be available until F 3/8 at
Ø
You
may have
multiple records for the same car because some of the data may be
different… for example, color, dealership, or cost for the same
make/model.
Ø
Before
submitting
your lab, you MUST be sure to list the entire input file location given
above
on your select statement. Points will be
deducted if you forget since the program will not be able to find the
input
file!
Ø
You
do not know
the number of records in the car input file, so you must check for end
of file.
INPUT
FILE RECORD LAYOUT for lab2buyerin.dat
You
create this file however you like using the below given data and
details. You should not need to check for
EOF
(although you can if you want) since you know the exact format and
number of
records in the file.
§
Your
name –
you determine the length and type
§
The
date you need
the car by – numeric length 6
§
The
maximum
amount you are willing to spend on a car – integer type; you determine
the length!
INPUT
FILE RECORD LAYOUT for lab2carin.dat
It
is possible that the data in this file will change, so don’t base your
program on the exact data values.
However, the format (i.e. types and lengths) of each field will
need to
stay exactly the same.
§
Dealership
– alphanumeric length 12 (ex. Tansky)
§
Make
–
alphanumeric length 10 (ex.
§
Model
–
alphanumeric length 10 (ex. Sienna)
§
Type
–
values include truck, car, van, sport, suv
–
alphabetic length 5
§
Color
–
alphanumeric length 10
§
Safety
Rating
– numeric length 1
§
Reliability
Rating – numeric length 1
§
Cost
–
numeric (integer) length 6
§
Name
of sales rep
– alphanumeric length 15
OUTPUT FILE LAYOUT
The output file report should look
similar to
the following with the name lab2out.dat (again, be sure to use this
name so the
grader doesn’t have to look up the name of the output file when
grading):
Output File Description:
Ø
You
only have ~80
(actually up to 85, I believe) positions across your printer paper. You need to be sure that your report will fit
on the paper. The above sample may need
to be changed somewhat to accommodate this.
You should create two column header lines should the data prove
too
long. That is, you could put the word
“Safety” on the line above directly over the word
“Rating” for the Safety Rating column header
Ø
The
output data
was put in a different order than the input data on purpose!
Ø
Be
sure to
include the blank lines as shown above
Ø
Create
your own PAGE
HEADING line to describe the report. It
needs
to be centered over the column headers
Ø
The
car data
should all line up nicely under the column headers
Ø
The
last line in
the output file should be the “END OF REPORT” line
Discussed in class;
there is
no external documentation required for this lab.
When you are
finished with
the lab, submit the following files for grading:
See Lab1 for
information on
how to use a submit command. Also, note
that programs must be submitted in source code form. For example, if
you submit
"lab2.acu" instead of "lab2.cob", you will have, at a
minimum, points deducted equivalent to submitting a day late (20%).
See Lab1 for
information
about deleting unnecessary files.
