Random Integer
rand/srand
Syntax
#include
<stdlib.h>
int
rand()
void srand(seed)
unsigned int seed;
Defined in
rand. c in rts. src
Description
Two functions work together to provide pseudo-random sequence gener-
ation:
•
The rand function returns pseudo-random integers in the range
Q-RAN D-MAX.
•
The srand function sets the value of seed so that a subsequent call
to the rand function produces a new sequence of
pseudo~random
numbers. The srand function does not return a value.
If you call rand before calling srand, rand generates the same sequence it
would produce if you first called srand with a seed value of 1. If you call
srand with the same seed value, rand generates the same sequence of
numbers.
