C 库函数 - rand() C 标准库 - <stdlib.h> 描述 C 库函数 int rand(void) 返回一个范围在 0 到 RAND_MAX 之间的伪随机数。 RAND_MAX 是一个常量,它的默认值在不同的实现中会有所不同,但是值至少是 32767。 声明 下面是 rand() 函数的声明。 int rand(void) 参
A more secure version of this function is available, see rand_s.Kopieren int rand( void ); Return Valuerand returns a pseudorandom number, as described above. There is no error return.RemarksThe rand function returns a pseudorandom integer in the range 0 to RAND_MAX (32767). Use the ...
MSDN中关于rand的描述"The rand function returns a pseudorandom integer in the range 0 to RAND_MAX (32767). Use the srand function to seed the pseudorandom-number generator before calling rand."rand()产生的伪随机数的范围是0到32767,一般想要产生比如[5,125]的随机数,可以这么写:int...
