Re: [Dev-C++] Quick flat-file searching and I/O

[David M. <ci...@ya...>]

Small problem.

Room descriptions are strings of variable length. Also the
exit descriptions
are included in the same structure(also varible length
strings). This can
cause the size of a room to vary greatly).

This might still work if I were to put a limit on how long
a room
description could be and padd shorter descriptions to make
it  equal the
standard size
