Keil C51 中产生随机数的方法

1. 摘录KEIL C51 帮助文件中的说明：

srand
#include <stdlib.h>
void srand (int seed);   /* random number generator seed */
Description:
The srand function sets the starting value seed used by the pseudo-random number generator in the rand function. The random number generator produces the same sequence of pseudo-random numbers for any given value of seed.

Return Value:

Example
#include <stdlib.h>
#include <stdio.h>                      /* for printf */

void tst_srand (void)  {
  int i=0;
  int r=279165921;

  srand (56);

  for (i = 0; i < 10; i++)  {
