#include "stdio.h"
#include "stdlib.h"
main()
{
 int magic,guess,counter;
 magic=rand();
 guess=magic-1;
 counter=0;
 while(magic!=guess)
 {
     printf("please input guess:");
     scanf("%d",guess);
     counter++;
     if(guess>magic)
     printf("****wrong****too lager\n");
     else if (guess<magic)
     printf("****wrong****too low\n");
 }
 printf("***right****\n");
 printf("%d",counter);
}

scanf……

scanf("%d",guess);.。。少一个&

错误很明显哦，这样的错误要注意，对基本的输入输出理解不够。

呵呵，谢谢各位
