Haha. Your question was actually a very good one. It took me at least 20 
mins to figure out, but I have found what is the problem.

When you use cin before you use getline, it leaves a newline character 
in the input (the console) and when getline is called it reads that 
newline character and returns with an empty line. To fix this, use the 
ignore function after you use cin and before you call getline:

cin.ignore(10,'\n'); // skip 10 chars until reaches '\n'

This will ignore all the '\n' characters so that getline will work properly.

Here is where to put it exactly:
