error with getline() function.

[aarjm123]

I am trying to use the getline() function and nothing is working I've tried doing fin.getline(name), and I get an error of "no instance of overloaded function matches the argument list" then I tried getline(fin, name) which compiles fine but it assigns "" an empty string as the name. The problem is in course.cpp in the ReadFromFile function

While I am not 100% sure, but, my guess is you need to flush out the buffer with a cin.ignore () and cin.clear() after you use cin (in main.cpp) then the cin.getline should work. Also, please remember to use the code tags it is nicer on the eyes.
