As C does not have an inbuilt function for generating a number in the range, but it does have rand function which generate a random number from 0 to RAND_MAX. With the help of rand () a number in range can be generated asnum = (rand() % (upper – lower + 1)) + lower // C...
Random numbers just numbers that lie within a range and any of the numbers can occur.In programming, we come through a lot of scenarios where we need to generate random numbers. Like for dice games, lottery system, etc. In the c programming language, there is an inbuilt method to take ...
用法: int random(int num); 程序例: #include #include #include /* prints a random number in the range 0 to 99 */ int main(void) { randomize(); printf("Random number in the 0-99 range: %d ", random (100)); return 0;

Random意思是返回一个0~num-1之间的随机数。 random(num)是在stdlib.h中的一个宏定义。num和函数返回值都是整型数。如需要在一个random()序列上生成真正意义的随机数，在执行其子序列时使用randomSeed()函数预设一个绝对的随机输入，例如在一个断开引脚上的analogRead()函数的返回值。
编译环境为：vs2013产生1到3的整型随机数的代码如下：#include<stdio.h>#include<time.h>#include<stdlib.h>#define max 3 //这个函数的意义为：随机生成最大的数为3#define min 1 //这个函数的意义为：随机生成最小的数为1int main(){int num;srand(time(0));num = rand() % (m...
