/* Hi Folks
I am really in trouble and very newbie in programming but hardworking. I
have coded an inventory program but the problem one function works again
when i exit from the program. Firstly, you add a new item then display all
items whic is second menu then you input 6 means exit program then program
will ask you again record a new item again. Please I need your help.
*/
I've made a couple of corrections to your code, it seems OK now. However, I
won't tell you the logic mistakes you did. I'll let you find your own
mistakes, comparing your code with mine.
I hope you'll see the syntax error in while ((ItemAdd=='Y') ||
(ItemAdd='y')). Did you compile this program? Didn't your compiler warn you
about this syntax error? And what compiler are you using?
Best wishes,
Engin Uysal
