Your program.

If you compile your program with "gcc -Wall -O2 -c foo.c" you will
see

  foo.c: In function `main':
  foo.c:16: warning: unsigned int format, different type arg (arg 2)
  foo.c:18: warning: unsigned int format, different type arg (arg 2)
  foo.c:48: warning: implicit declaration of function `getch'

So you are passing a pointer to the wrong kind of object to scanf().
Therefore scanf() overwrites memory you did not mean to.

Nuke the "short" and you will have a correct program.

PS: There are some problems with scanf() if I remember things
    right.  They have to do with the return value and are being
    worked on or have already been solved for the next release.
