What error message are you getting? It worked fine at my end apart apart from a few stylisitc quirks that I've tried to smoothen out. Make sure that your .txt file and compiler are in the same root folder. Over time, also learn to overload the extraction operator >> (instead of getAssignments()) and the insertion operator << (instead of displayAssignments()). And keep the # of courses as a global variable, SIZE in my example, so that if ever the # of courses changes you can just update one variable accordingly:
