Well, you might try something like this. And, if you are feeling really
enegetic, you can even convert it into a header file (something like
random.h). Anyway
#include <stdio.h>
#include <time.h>
void main (void)
{
int r1;
int r2;
/*Starts randomization*/
srandom(time(0)&0xff); /* This seeds the Random number generator
with something derrived from the system clock.
This way, the random number changes.
Unfortunatly, because the time changes only
once/second, if you put this program into a loop
(ie while(1)), when you finally break it, your
screen will be filled with the same number. Other
ways to seed it include time between kbhits or
the value of a few getchars(), but time is
probobly the easiest.*/
r1=time(0)^random()^random();
/* This makes Random equal to the value of time
raised to the power of a random number rasied to
the power of a random number. This gives you one
random number*/
r2=r1%=16;
/* Since 'r1' is probobly a __tad__ bit too big
for any use in your program, we limit it to a
value using this line. Since I was using this
example to change the color of text in my program
I set it to sixteen (cause there are 16 colors).
What actually happens is that r1 is divided by 16
and remainder will be x over sixteen. The modulus
(%) function returns that x.*/
printf("%d\n", r1); /* Self Explainitory*/
printf("%d\n", r2); /*See above*/
exit(0); /*See above :>) */
}
I'm sorry if this sounds somewhat patronizing or obvious, but from your
post I was having trouble getting a feel for your ability level. Good
luck.
