C++ classes HELP. I have this coding homework and I dont understand what it is wanting differently. It is a program that reads in a file that is basically a course directory states how many classes are in the file then, class code [like MATH or EECS], then code number, number of students and then all student id's for that class. I thought that the section where it is reading in the file would work but it is saying the courses.[blah] has not been declared.... So not sure what I should do... in order is the executive.cpp file, then exectutive.h and then main.cpp
