Classes anyone please?

Hi guys!!!
everytime I try to read the course description from the file it crashes, (fin>>Des; (*cptr).setclassD(Des);) I even used the getline function and still not workling ... maybe this a very easy fix but I have been trying to fix it for hours and now I'm turning to you guys . the test file should look like " CPE 202 Introduction to computer "
any thought would be great thanks a lot

where is the memory allocation for course::classD.
line #32: allocate memory for classD like u did for course::dept
