Array not reading from File

[cplus2010]

Iam new to c++, iam writing this program with 3 files called header file, class implementation file and main cpp file.

Iam using array to read from 2 files file food Inventory get the data, and other file name rates has tax rates info, i got all the 4 cases working fine, except case 5 I got struck, I really appropriate if you can look at my code, need your help. This is main CPP file , if you want look at other 2 files let me know

Thanks in advance.
