GPA PROGRAM

1) Define & analyze problem

standard point system:
A = 4
B = 3
C = 2
D = 1
F = 0
+ means add .3 (except not for A, F)
- means subtract .3 (don't use on D, F)
S, U = ignored by GPA computation

take course grade, convert it to point value, multiply by credits
add all those together (total points)
add all credits together (total credits)
gpa is total points / total credits

SAMPLE RUN ---------------------------------
Welcome to the GPA Program
(assume a standard point system)

How many courses? 4
for each course enter the grade & credits separated by space
for course 1: A 3
(points = 12)
for course 2: B 1
(points = 3)
for course 3: B+ 4.5
(points = 14.85)
for course 4: D 3
(points = 3)

(total points = 32.85)
(total credits = 11.5)

GPA is 2.86

Not on AcPro

---------------------------------------------

2) Design the solution

Pseudocode for algorithm

display welcome message
get # of courses
repeat # of courses times
	ask for grade & credits
	convert grade to points
	multiply points by credits
	add to total points
	add credits to total credits
gpa is total points divided by total credits
display gpa
if (gpa < 2) display "on AcPro"
otherwise display "not on AcPro"
if (gpa >= 3.5) display "Dean's List!!! Yay!!"


display welcome message
prompt for # of courses
read numCourses
initialize totalCredits to 0
initialize totalPoints to 0
initialize count to 1
while count <= numCourses
	ask for grade & credits
	read grade
	read credits
	convert grade to points***
	points gets points * credits
	totalPoints gets totalPoints + points
	totalCredits gets totalCredits + credits
	count gets count + 1
gpa gets totalPoints / totalCredits
if (gpa < 2) display "on AcPro"
otherwise display "not on AcPro"
if (gpa >= 3.5) display "Dean's List!!! Yay!!"


***convert grade to points
get first letter of grade
if (first is A), points gets 4
if (first is B), points gets 3
if (first is C), points gets 2
if (first is D), points gets 1
if (first is F), points gets 0
if there is a second character
	if second is '+' and first not an A or F
		add .3 to points
	if second is '-' and first not an D or F
		subtract .3 from points
return points as result
