Question

求c语言大神帮我看看这个二分法查找有什么问题 刚输入就结束了这个函数

int SearchSNUM(Student team[],int n)//定义学号查找
{
char k[20];
printf("请输入你需要查找的学号：\n");
scanf("%s",&k);
int low=0,high=n-1,mid;
do
{
fflush(stdin);
mid = (low high)/2;
if(k==team[mid].SNUM)
{
printf("学号为：%d\t",team[mid].SNUM);
printf("姓名为：%s\t",team[mid].NAME);
printf("房号为：%s\n",team[mid].RNUM);
return mid 1;
}
if(k<team[mid].SNUM)
{
high = mid-1;
}
else
{
low = mid 1;
}
}while(low<high);

Answer 1

int SearchSNUM(Student team[],int n)//定义学号查找
{ char k[20];
  printf("请输入你需要查找的学号：\n");
  scanf("%s",&k);
  int low=0,high=n-1,mid;
  do
  { fflush(stdin);
    mid = (low+high)/2;
    if(strcmp(k,team[mid].SNUM)==0)        //需包含string.h
    { printf("学号为：%d\t",team[mid].SNUM);
      printf("姓名为：%s\t",team[mid].NAME);
      printf("房号为：%s\n",team[mid].RNUM);
      return mid+1;
    }
    if(strcmp(k,team[mid].SNUM)<0)
    { high = mid-1;
    }
    else
    { low = mid+1;
    }
  }
  while(low<high);
  return -1;
}
