Access Violation Error Help

[Shadow_Govt]

I keep getting this message that I cant figure out how to fix.

Here is the error:

First-chance exception at 0x6380f8bc (msvcr90d.dll) in Final.exe: 0xC0000005: Access violation reading location 0xcdcdcdcd.
Unhandled exception at 0x6380f8bc (msvcr90d.dll) in Final.exe: 0xC0000005: Access violation reading location 0xcdcdcdcd.

And the symbols are not loading for: kernel32.dll and ntdll.dll.

What did I do wrong? ( I know that it has something to do with strlen and the buffer in the GetPet function.)

(if my code looks funny it is bucause it is an assignment for college. SOme of the things I have done here are a requirment; sorry. And I know that it has some C in it. This is something that I have been informed by my instructor as part of the learning process; vectors, structs, blah, blah, will come later next term.)

Here is my code:
