Mini project supermarket billing system in c++ source code download

This mini project is written in C++ where you find mainly two classes one class item another class amount and class amount is inheritance form class item.It is simple console application without graphics. From this project you learn file handling in c++ and use of stream class.And main defect of this program is that goto label  is used to jump form one menu to another menu and separate function for editing  and deleting items are not used.So,if you want to make it your school project or college mini project then modify it ,make separate function for editing and deleting and also try to use while loop instead of goto label .Any suggestion and help for this project is appreciated .
Here is the source code ,copy and compile it in gcc with code::blocks IDE.

  8. it's correct but not efficient, because goto statement is used, which is not considered to be good programming ...
