This is pretty basic stuff here, but there are a number of ways to do
what you want.

1) Represent each tile as a structure, indicating not only the type of
tile but what "objects" are on it.
2) Maintain separate arrays, one for the tiles, and one for the
"objects" on the tiles.  The map display routine simply displays one
array and then the other on top of it.
3) Don't redraw the entire map each move; just redraw the tile your
character is on and the one it moves to.  This saves on time because the
map only needs to be drawn once.
4) More complex solutions not covered here.

Implementations of the above are left as an exercise for the reader.
