Phase 1) GPA Problem Analysis

Write a program to compute a GPA, based on course grades and credits.

SAMPLE RUN:
How many courses? 4
Enter letter grade and credits for each course, such as A- 3.0:
1) a 3
2) B- 4
3) c+ 3
4) B 4.5
GPA is 2.98

PROBLEM ANALYSIS:
a => 4 * 3 = 12 points
b- => 2.7 * 4 = 10.8 points
c+ => 2.3 * 3 = 6.9 points
b => 3 * 4.5 = 13.5 points
============================
43.2 total points / 14.5 total credits

2) Design Solution (pseudocode)
- prompt for # courses
- read numCourses
- prompt for grades and credits
- set courseNum to 1
- repeat until courseNum > numCourses
	- display courseNum and ")"
	- read grade
	- read credits
	- add credits to totalCredits
	- convert grade to points  (!! needs more detail)
	- add (points*credits) to totalPoints
	- add 1 to courseNum
- display "GPA is"
- display totalPoints / totalCredits

Convert grade to points:
if grade is A, points = 4
else if grade is B, points = 3
else if grade is C, points = 2
else if grade is D, points = 1
else points = 0
if there's a + and not A, add .3
if there's a - and not D, subtract .3
return points
