关于c语言中的rand()

因为随机数种子不变用srand设置一个不同的随机数种子型旁即可改袜例程/* rand example: guess the number */#include #include #include int main (){ int iSecret, iGuess; /* initialize random seed: */ srand ( time(NULL) ); /* generate secret number: */ iSecret = rand() % 10 + 1; do { printf ("Guess the number (1 to 10): "); scanf ("%d",&iGuess); if (iSecret卜歼橡iGuess) puts ("The secret number is higher"); } while (iSecret!=iGuess); puts ("Congratulations!"); return 0;}
