Everything looks good to me, so i'm obviously not understanding something.
Any suggestions?

The input file should have this format and include over 20 students for testing purposes:
g0, g1,...g9 should be 10 grades ranging from 0 to 100 
First Middle Last
g0 g1 g2 g3 g4 g5 g6 g7 g8 g9
First Last
g0 g1 g2 g3 g4 g5 g6 g7 g8 g9

Using namespace even before including the standard libraries?

Yeah, it looks neater to me... lol I usually try to format according to length in descending order. I developed this habit a while ago. I have just started teaching myself about classes and such so it's not in order now, though.

Changed line 1 of StudentType.h from #ifdef STUDENTTYPE__H to #ifndef STUDENTTYPE__H.

Declared int n; below the default constructor StudentType(); within the main function of Program04.cpp

changed 'student[n].setGrade(grade, i);' to "students[n].setGrade(grade, i);' ----- (added the 's' to students)


Deleted & from the parameter of void getFormat(string& name);

Changed Line 16 or the header file from void print(std::ostream& = std::cout) const; TO void printLine(std::ostream& = std::cout) const;
