函数名:random 功 能:随机数发生器 用 法:int random(int num);程序例:include <stdlib.h> include <stdio.h> include / prints a random number in the range 0 to 99 / int main(void){ randomize();printf("Random number in the 0-99 range:d\n",random (100));return 0;} ...
需要首先使用随机数“种子”初始化，srand函数：＃i nclude <stdlib.h>＃i nclude <stdio.h>＃i nclude //使用当前时钟做种子void main( void ){int i;srand( (unsigned)time( NULL ) );//初始化随机数/* 打印10个随机数. */for( i = 0; i < 10;i++ )printf( " %d\n", rand(...
double r = (rand()%1000)/1000.0
