CECS 174 Project 6 - Due in lab on Tuesday, 11/18/03
The program you wrote for Project 5 works fine for a small class where the number of scores that needs to be
entered is sufficiently small. This project is designed to handle larger classes. The specification of this project
extends from Project 5 in four ways:
1. The number of scores may be large, and they may be stored in a file as a sequence of integers, separated by
blanks. Therefore, no prompting for input is needed. Use input redirection on UNIX command instead.
2. Long parameter list is in general undesirable. Use an array to implement the grade counters to avoid long
parameter list.
3. Besides showing the number of grades in each grade level, compute and report the percentage of grades in
each level as well. The percentages are computed to integers with the normal rounding (e.g., 13.34 is
rounded to 13, whereas 13.76 is rounded to 14.)
4. Draw a bar graph to show the distribution of grades in percentage.
Grading scale:
A: score >= 90
B: 80 <= score < 90
C: 70 <= score < 80
D: 60 <= score < 70
F: score < 60
When your program executes with the data file shown below, it should produce output as in the following
sample dialogue:
Scores input:
55.00 80.50 37.00 98.00 91.50 67.90 88.00 74.00 81.05 62.50
33.70 93.00 95.00 84.00 73.00 81.00 77.50 70.20 90.00 55.00
74.00 66.00 73.00 79.00 62.00 84.00 86.00 76.50 91.00 64.00
Average score = 74.78
Standard Deviation = 15.43
Grade Number of Students Percentage
A 6 20
B 7 23
C 8 27
D 5 17
F 4 13
