Offline Shop Compilation Error [C++]

[leo2993 27]

As the title says, I have a small problem while I try to compile the source with the modifications of the "offline shop" system called [RELEASE] Offline Shop - Koray...

This is the declaration of some variables in the file called "input_main.cpp".

I have in mind that they are functions that the tutorial lacks because I do not find them in the "include" files of the "input_main" file.

Here the picture:

 

 

Does anyone have any idea what might happen? Or someone has the functions declared in some file?

Thank you.

There are 3 Errors. Please share your  input_main.cpp  or at least the exchange function
