0. Introduce Random Number Generators #include <stdlib.h> 1. How to generate a random number in a given range in C. Examples: Input : Lower = 50, Upper = 100, Count of random Number = 5 Output : 91 34 21 88 29 Explanation: lower is the lower limit of the ...
Generate random number Returns a pseudo-random integral number in the range between 0 and RAND_MAX( 32767) rand函数详细链接 返回值int无参数,包含在stdlib.h函数库中 可以看到rand可以生成一个0~RAND_MAX的随机数。 用rand生成了100个随机数。看来并没有什么问题。
Hi, i would like to know how to generate a random number by using C. I wrote the following code : srand(time(NULL)); int x = rand()%(4-1)+1;
