its supposed to be a program to display a main menu,then a display, calculate the lunch order for the customer to pay,make reservations and save it to a file then display it.Also it get the stock for how many lunches will be served for the day for specific dishes then update it by telling how many lunches are left after every purchase.This part I'm having alot of trouble with so i need help with this.Any other suggestions for any functions or for anything that make my program more efficient are welcome.Thanks. #define MAXITEMS 31

Could you please use code tags and specify what you need help with? I know C++ skips white-space but don't you think you're taking it to far after i=i+1;?
