Cannot read quantity

akif13 (18)
Hello guys, I need your help to solve this. I don't know why it skipped at line 48 without letting user to input the quantity. Is there something wrong with my syntax? Thanks in advance.

cin >> size fails because you inserted a letter and size is an int. That will set the fail flag of cin so that all future read operations on cin will fail (return immediately).

I don't see that it skips line 48. What I see is that you calculate totalprice after it is displayed
