You have to include <time.h>
then
...
srand(time(NULL));
int ran = rand()%0x7fff + 1; // this will give you a random number between 1 and 7fff Best Regards,

then
...
srand(time(NULL));
int ran = rand()%0x7fff + 1; // this will give you a random number between 1 and 7fff Best Regards,

srand(time(NULL));
int ran = rand()%0x7fff + 1; // this will give you
//a random number between 1 and 8000
Correct is:
srand(time(NULL));
int ran = rand()%(0x7fff - 1) + 1;
//or
int ran = rand()%0x7ffg + 1;
// this will give you
//a random number between 1 and 7fff

Well, if you started correcting such little things ...
Taking this from your post:
//or
int ran = rand()%0x7ffg + 1;
// this will give you
//a random number between 1 and 7fff
That hardly can get you anything, it must be e instead.

As I think is some thing like following?
int rnd(x,y)
{
return rand()%(y - x) + x;
} John Fill

int rnd(x,y)
{
return rand()%(y - x) + x;
