i have problems with if- else statements

MissaelV10 (3)
how can i make this code works?
it is supposed to give me "Unable to make a diagnosis" only when i answer the questions with characters other than 'y' or 'n', but i don't know how to do it.
can somebody tell me what's wrong?
A response will be very appreciated.

i just have 2 weeks learning c++
