This looks to be the problem.

Declared like this
CODE

collegeCourse(const string& id, int credits, char score);


implemented like this
CODE

collegeCourse::collegeCourse(string& id, char score, int credits)


notice that the char and int variable has been swapped. The should be in the same order. Either
CODE

collegeCourse(string& id, char score, int credits)
or
collegeCourse(string& id, int credits, char score)

for both the declaration and definition

change this: collegeCourse::collegeCourse(string& id, char score, int credits)
to this: collegeCourse::collegeCourse(const string& id, int credits, char score)

great thanks. Now i am having the trouble i think with my operators can anyone help me with this.


I need have my output look like this but I can't get it to pull the average from my arrray.

and your output would look like this:
The average of 7 and 26 is 16
The average of 39.25 and 2.01 is 20.63

The average of
ENG101 Grade: A Credits: 3 Honor points: 12
PSY251 Grade: B Credits: 3 Honor points: 9
is 10.5

The average of 7, 26 and 100 is 44
The average of 39.25, 2.01 and 4.2 is 15.1533

The average of
ENG101 Grade: A Credits: 3 Honor points: 12
PSY251 Grade: B Credits: 3 Honor points: 9
HIS301 Grade: D Credits: 4 Honor points: 4
is 8.3333
