In order to correct the "getline" bug in Microsoft Visual C++, Version
6.0 , carefully perform the following steps:

 1. Right click on the word string in the #include <string> in your
    header
 2. Choose open document string from the resulting pull down menu
 3. Click on Edit, then Find
 4. Enter the following line in the Search box:
else if (_Tr::eq((_E)_C, _D))
 5. Make the following changes in code as shown:
original modified
else if (_Tr::eq((_E)_C, _D))
     {_Chg = true;
      //_I.rdbuf()->snextc();
      // (this comments out the defective instruction)
      _I.rdbuf()->sbumpc(); // corrected code
      break; }
 6. Save and close the string header file.

You should only have to do this once on your home PC.  Unfortunately, if
you want to do this in a student account, you may have to do this each
time if you move to different machines, or if the machines have been
re-imaged.
