樱花吃了有什么好处:请问谁有C语言的反猜数字(让电脑来猜)的源程序

#include<iostream.h>
#include<conio.h>
#include<stdlib.h>
void main()
{int a,b,m,k;
char ch;
again:
k=0;
_cputs("\n请输入你想好的数的范围：_至_\n");
cin>>a>>b;
m=(b+a)/2;
_cprintf("是%i吗？如果是，请输入\"y/Y\";否则，请输入\"<\"或者\">\"。\n",m);
do
{ch=_getche();k++;
if(ch=='<')a=m;
else if(ch=='>')b=m;
else
{_cprintf("\nYes！我猜对了！我猜了%i次",k);
_cputs("\n还想玩吗？（Y/N）\n");
ch=_getche();
if(ch=='Y'||ch=='y') goto again;
else {_getche(); return; }
}
m=(b+a)/2;
_cprintf("\n是%i吗？如果是，请输入\"y/Y\";否则，请输入\"<\"或者\">\"。\n",m);
}while(1);
}

好像在这里你搜一下,就可以了吧.

是猜大小还是猜几A几B的东西呢。。。大小的当然简单，几A几B的东西还是稍微有点难度的。。。全国信息学奥林匹克今年的冬令营就考了这题目。。。

A几B几需要的话邮件联系我。。。先尝后给分
