Answer 1

static string name;

As it is static, this line only declares name - you need to define it too. Simply place this below your class definition:

string CPractice::name;

If you end up moving your class to a corresponding header and implementation file, make sure you place this definition in the implementation file. It should only be defined in a single translation unit.
