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. Required header: <stdlib.h> Example 复制代码 // crt_rand.c // This program seeds the random-number generator /...

Therand() function returns a pseudo-random integer in the range 0 toRAND_MAXinclusive (i.e., the mathematical range [0,RAND_MAX]). Thesrand() function sets its argument as the seed for a new sequence of pseudo-random integers to be returned byrand(). These sequences are repeatable by...

In order to get reproducible behavior in a threaded application, this state must be made explicit; this can be done using the reentrant function rand_r(). Like rand(), rand_r() returns a pseudo-random integer in the range [0, RAND_MAX]. The seedp argument is a pointer to an ...
