termination of console application before a getline statement

[olaf the huggable]

This is a program for inventory. There are functions for the cashier and some for the administrator.
My problem here is that the termination of the console application happens before i take the input of an item description.
The line is "getline(cin, Description[STOCKS-1]);" given that the initial value for STOCKS is 4, but incremented before the getline. This line can be found in the function void stocks::Products1() or at line 230

You cannot increment STOCKS because the array Description does not magically expand.

Suggestion: Turn line 26 to 30 into a struct and use a vector for the storage.
