Random number:

//#include <stdlib.h>:rand, Srand//#include <time.h>:timeSrand0);p rintf ("%d\n", Rand ());//rand corresponds to Srand, and Rand's random values do not change as long as the seed of Srand remains unchanged; Rand's range is 0-int.Srand (Time (NULL)); Srand (unsigned) printf ("%d\n", Rand ());//The time function returns the current time (in seconds), and if the parameter param is not bull, it is assigned to Param. So the random number will always change (really random)printf"%d\n", rand ()% -+1);//Generate 1-100 Random number: rand ()% 100 is 0-99
