if you read everything from std::cin you won't need to bother with file name
handling, just do something like
  $ ./a.out < mydata.xyz

we're talking the same thing.  :-)  the size of your matrix, followed by the
data values.

my (elderly) gcc manual does not list '#pragma once' but the clue seems to be in
the name.  as to 'stdafx.h' -- it's not a "standard header" here, Windows
perhaps?  I'd get rid of the include, and 'stdio.h' is probably included
already.

anyway, the source you posted does not compile, so it's clearly not meant to be.
 on a different subject, when will there be news/code for the pulley stuff?
thinking that, with minor modifications, it would be useful for modelling
tracked vehicles.  :-)
