猜谜游戏（随机数）

#include<stdio.h>
#include<stdlib.h>
#include<time.h>int main(){srand(time(0));int number = rand()%100+1;int count = 0;int a;do{scanf("%d", &a);count ++;if( a<number){printf("too smalln");} else if ( a>number){printf("too largen");}} while (a != number);printf("congratulation!nnumber is %d,your guess %dtimes", a, count);}

<stdlib.h> include (rand)function
<time.h>

(rand)function 随机产生一个数，但是这个数很大，需要用到取余%来获得需要的区间
%100 [0,99]
%100 +1 [1,100]
