Decryption is simply the reverse of encryption - so if your encrypt added some constant, you then need to subtract to reverse it.
If you dance barefoot on the broken glass of undefined behaviour, you've got to expect the occasional cut.
If at first you don't succeed, try writing your phone number on the exam paper.
