RE: [Dev-C++] question about file

[youngs <you...@ut...>]

what you read is '2', '3', '3', not 2,3,3, so get wrong result.
you should use :  c=3Dgetc(nombre)-'0' to get correct digital.

i can't see any problem with your logic though i would use
while ( !feof(nombre));
Rather than
while (c !=3D EOF);
Perhaps you should debug and see what is being read from the file. also
consider how the file is layed out.
