To place a lower bound in replacement of 1 on that result, we can have the program generate a random number between 0 and (high - low + 1) + low.I realize how confused you might be right now, so take a look at the next sample program I promised, run it, toy with it, and ...

printf("Ten random numbers from 0 to 99\n\n");for(i=0; i<10; i++)printf("%d\n", rand() % 100);return 0;} 除以上所说的之外，补充一点就是srand这个函数一定要放在循环外面或者是循环调用的外面，否则的话得到的是相同的数字。MSDN中的例子。// crt_rand.c // This program ...
The seed value determines a particular sequence of random numbers to generate when calling the rand function. If a program always uses the same seed value, the rand function will always get the same sequence of numbers from the rand function. If the srand function is not used to provide a ...
