Shop Management System Project in C++

Instructions:

Below mention code is compiled in Code Blocks , Visual Studio 2015 and TC .Output snap is attached.. If any problem you feel and want explanation feel free to contact.

You must include a file "list.txt",You can include data in this file "list.txt" like below,

12001;salt;20;good;1022;
12002;sugar;35;excellent;1104;
12003;Milk;42;excellent;500;
12004;Rice;23;good;2523;
