For random numbers try using something like this:
put srandom((int)time(NULL)); at the beginning of your program if you do
not want to get the same number numbers each time you run your program and
to get a random number to some limit x use this
random() % x; which gives you random number from 0 to x-1;

About the program size try compiling with the -s option. It should be much
smaller, but not as small as from real mode compilers.
