C++ end of file error?

[Isolated]

Hello, this is the error I am receiving.

My program is crashing on the default data:
> terminate called after throwing an instance of 'std::out_of_range'
> what(): basic_string::substr
> Aborted (core dumped)
I have no idea what is wrong with it, I need some help trying to find it.


It is in my main loop and is an end of file error.

So here is my main.

Thank you very much, I have been working on this for a very long time and am new to C++.

This program will calculate haul potential, the distance in standard units to the planet, and 
the planet with the highest resources(HP).  The closest and first encountered planet with the most
profit will be selected first.

Post more code. Several functions are used in this snippet.

Ok I have edited it and posted more code.

Thanks.

On the first glance, after getline at line 157 encounters the end of file, it sets the stream error indicator (which you don't check), coorLine is an empty string. .find() fails and returns npos, .substr() fails and throws the exception.
Try to remember where you learned to write "while(infile)" and avoid that like fire.

Yeah I don't know how to fix that while loop.
