i'm majoring in comp. science so i'm taking programming. classes are pretty straight forward, but i am stomped on this. can you help me ?

I can't help you since I haven't touched on classes yet..

ya, i commented it out to see if the error would go away, but it didn't

the first file is declaration(.h), second is implementation, third is test. the error is in the test file; the last code

i'm getting the same error for some reason. the only error there
