Random Number in a specified range

I know how to get a random number using the time as a seed, but how can i have it be between two speficied numbers? (say, 65 to 90)

You want random capital letters... chars from 65 to to 90....
Try:

PHP Code:

---

unsigned char r=0;
while (r<65){
      r = rand() % 91;
}
printf("%c \n" , r);

Lol, so you saw that :p Thanks for the help.

Is it possible to have multiple ranges? ( I am trying to get any alphanumeric character)

Code:

---

r = rand() % (max - min) + min

---

Z.

Thanks, that helps a lot.
