i have win xp home edition... and my compiler is dev-C++ although i dont think its a compiler issue....
This is my project needs: (my attempted code follows)
(
Write a main function with all required internal functions subprograms (defined later) that tracks your college classes, grades and GPA. Sample I/O is shown below. Your lab instructor will give you final data to run.
Input: Engl325 C 2 (class, grade, hours)
Chem111 B 4
CS110 A 4
Phys115 D 4
Stat215 F 3
Phil201 W 0
QUIT or quit
Output: List of My Courses
Class Hours Grade GP
Chem111 4 B 12
CS110 4 A 16
Engl325 2 C 6
Phil201 3 W 0
Phys115 4 D 4
Stat215 3 F 0
Total 20 38 GPA = 2.23
Rules:
1. You must define an enum type to handle all grades (A,B,C,D,F,W,I). Each grade is input as a char, then you must change the char via a switch-stmt to your enum type.
2. Your main function must contain the following subprograms:
accepts return stmt? Out or InOut?
hours and grade for 1 course GP
hours, GP (2 arrays) GPA
3 arrays: sorts ascending on Class name all 3 arrays
prints heading void
skips to next line; print 1 line of table void
3. Use cin to input each class, grade, and hours, 3 items per line.
4. Sort the classes in ascending order for strings: CS110 < Engl325 < Phys115, etc.
Your lab instructor will talk about sorting on array.
5. Make your program stop when either quit or QUIT is entered as a class.

}to further explain my problem...
The program compiles just fine... the problem is with the output..
say you input math A 3 for math an A in the class and 3 hours
it returns the value A and you input more
after 2 or 3 inputs you have to type quit 2 times, not just one for the program to quit. Also once you do this... it just states the line
"Enter a course, the letter grade received, and the credit hours" over and over with the last letter value "A" or whatever in between each of the lines... It continues this until i get an error message from windows (it also looks around like 50 times) thats why i am curious if i did my arrays wrong or my bubblesort or what?
Thanks everybody who looks at it or tries to help or anything.
