Why do I get a strcpy runtime error in my code?

I've been trying to make my code work on Windows (moved from the Mac) and for some reason I get a runtime error related to my strcpy call.

Please help!!

It would help if you would post the error message, but since you're saying you're going from Mac to Windows, it would point to a line ending issue. Convert your custData.txt file to have Windows end-of-lines (CR + LF) and retry it that way.

It could be that your line

input.getline(tmpString, 70, '\n');

is just looking for the \n when it should be looking for a \r\n or something similar because of the Windows line ending being different the Mac line ending.

The most likely reason is that one of the five strtok() sequence calls is returning NULL because there aren't enough fields on the line.

I don't get a runtime error, but I get a compile time error (on Linux) because you didn't

#include <cstring>
#include <cstdlib>

in main.cpp

or

#include <cstring>

in Cust.cpp

After adding those it compiled and ran fine for me...

What precisely is the error you get?

You didn't specify in which line of the output file the crash happens. Could it be that the last line is missing the carriage return (\n) at the end?
