Can Anyone Find my mistake?

Prog24 (25)
My program is supposed to read in a file that has a breakfest menu including foods like eggs and bacon. The user can select as much as many items as theyd like but can only select them once.

I then I have to provide a receipt include the items that were purchased, sales tax and then total owed. This is where Im having a problem. My math works, but Im having trouble properly bringing my items in that I have selected and properly producing the receipt.

I provided my whole code below instead of just the receipt function incase someone notices anywhere else I screwed up.

Function printCheck is never called.

Thanks for the reply!

Would you mind explaining to me as to how to properly call printCheck so that I can get my receipt to look something like this:

Sales Receipt
1 Bacon and Egg $2.45
1 Coffee $0.50
-----
$2.95
Tax 0.14
-----
Total $3.09

I meant that the function was not called in main().

The parameter menu[] is not used in the function, either.
