c语言用随机数初始化10*10的二维数组

#include <stdlib.h>#include <stdio.h>#include <time.h>#define
# include “stdio.h”# include “stdlib.h”# include “time.h”int main
voidGetRandom(){inti,dat[10];for(i=0;idat[i]=rand()%5+1;}
完整的代码,红圈处就是从上面100个数字中抽取到的数字:#include <stdio.h>#include<stdlib.h> &
很明显了.rand()%100+10产生的是[10,110)之间的随机数.rand()%(100-10)+10=>rand()%90+10.
inta,b;a=rand()%10;b=rand()%10;printf("%d+%d=%d\n",a,b,a+b);
#include#includevoidmain(void){floaty[]={0.18,0.00,0.16,0.14,0.04,0.06,0.10,0.10,0.14,0.08};floats;i
srand(int)来设种子,然后每次rand()返回一个随机数.注意要包含#include<stdlib.h>头文件,因为用到了srand函数#include <time
include <stdio.h>include <random.h>void main(void){ &nbs
srand((int)time(NULL));设定随机数种子rand()%100;产生0-99的随机数.高级点的,假如要产生16-59之间的数,你可以这样写:rand()%44+16(这里44由59-
#include#include#includeintmain(){inti,n,m;printf("请输入n,m(逗号分隔):");scanf("%d,%d",&n,&m);srand((unsig
#include#include#includeintmain(void){srand((unsignedint)time(NULL));printf("%d%%\n",3+rand()%7);
#include#includeintmain(intargc,char*argv[]){intn=500;for(inti=0;i
#includesrand(time(NULL));i=rand();现在i就是一个随机值了如果随机值要求在一个范围内,比如0-100i=rand()%101;

and(产生随机数)相关函数srand表头文件#include定义函数intrand(void)函数说明rand()会返回一随机数值,范围在0至RAND_MAX间.在调用此函数产生随机数前,必须先利用
一、把浮点数先看成整数,即区间为:-489到327之间二、把-489当做0,327就是327+489=816三、这样生成的伪随机数去模817,会得到0-816间的数X四、把结果转换成对应的数,Y=X-
inta;srand((int)time(NULL));a=rand()%1000+1000;---------------ok了!
