C rand() function C rand() function - Pseudo-random number generator The rand() function is used to compute a sequence of pseudo-random integers in the range [0, {RAND_MAX}]. The value of the {RAND_MAX} macro shall be at least 32767. Syntax rand() function int rand(void) Parameter...
time_t的类型是整数还是浮点数? Do I need '(unsigned int)' before 'time(null)' in the srand function in c? time()返回类型为time_t的变量。实现与您的编译器上对应的类型大小是定义的。您必须检查编译器文档。 it is said that in addition to stdlib.h and time.h libraries I have to include ...
rand函数范围：在某些平台下（例如 Windows）RAND_MAX 只有 32768。如果需要的范围大于 32768，那么指定 min 和 max 参数就可以生成大于 RAND_MAX 的数了，或者考虑用 mt_rand() 来替代它。rand函数不是真正的随机数生成器，而srand()会设置供rand()使用的随机数种子。如果你在第一次调用rand()之前...
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...

rand() and srand() in C - rand()The function rand() is used to generate the pseudo random number. It returns an integer value and its range is from 0 to rand_max i.e 32767.Here is the syntax of rand() in C language,int rand(void);Here is an example of ra
The rand() function shall compute a sequence of pseudo-random integers in the range [0, {RAND_MAX}] with a period of at least 2**32. The rand() function need not be reentrant. A function that is not required to be reentrant is not required to be thread-safe. The rand_r() functi...
