just for case 4 in switch, I would like to use function instead of write it into main. The function should accept part of the customer's name as an argument. Can someone help me?

What do you need help with? Do you know how to write a function? Do you know how to pass variables into and back from functions? If not I suggest you read the tutorials contained in my signature. They should help. Otherwise ask specific questions.

i know how to use function a bit, but don't know how to pass structure array into a function and call it into main.
