i am trying to print report for a hardware store using parallel vecrors but it says file not found ?? why ?

This line is causing the troubles: incode.open(" C:\\Dev-Cpp\\inventory.txt"); Do you see the space between the ' " ' and ' C '? Delete that one. Of course the file should still exist at the given locating :)

The proper way to check if a file is open if with the is_open() function. For example: if (!incode.is_open())

incode.open(" C:\\Dev-Cpp\\inventory.txt");

is that space between " and C: there in the original code also? you can remove that space and try.
