C int rand
Web在C语言中,我们一般使用 头文件中的 rand () 函数来生成随机数,它的用法为: int rand (void); void 表示不需要传递参数。 C语言中还有一个 random () 函数可以获取随机数,但是 random () 不是标准函数,不能在 VC/VS 等编译器通过,所以比较少用。 rand () 会随机生成一个位于 0 ~ RAND_MAX 之间的整数。 RAND_MAX 是 头文件中 … WebDefinition and Usage. The randint () method returns an integer number selected element from the specified range. Note: This method is an alias for randrange (start, stop+1).

Web总结来说,可以表示为:int num = rand () % n +a; 其中的a是起始值,n-1+a是终止值,n是整数的范围。 一般性:rand () % (b-a+1)+ a ; 就表示 a~b 之间的一个随机整数。 若要产生0~1之间的小数,则可以先取得0~10的整数,然后均除以10即可得到“随机到十分位”的10个随机小数。 若要得到“随机到百分位”的随机小数,则需要先得到0~100的10个整数,然后 … WebAbout.
