I dont have time to sit down and compile it but I notice that in your header file you have:
and in the .cpp you have
Employee::SetHours( int hours )
The parameters should be the same, so they both should be SetHours(int)
Same with SetPayRate
also, before Employee:: you should have the return type of the function too
i.e. void Employee:

etHours( int hours ){
for name, in your while loop you just have name[i++], I assume you meant lastname[i++]
That should take care of most of your errors, at least I think. Its 5:30am and ive been working all night, so I hope I'm not too wrong. Good luck!
