我给电脑输入一个答案， 然后让玩家才我输入的数字， 如果他猜高了我会提示他， 猜低了也提示， 但是如果猜超过8次的话， 程序就自动显出答案， 如果按0的话就退出。

我现在的程序其他的都没问题，除了玩家猜了8次后，程序还是不显答案， 还让玩家继续无限猜下去， 不知道问题出在哪里了， 大家帮忙看一下，谢谢啦

#include <iostream>
using namespace std;

int main ()
{
    const int num=56;
    int guess, i, flag=0, count=1;
   
    cout<<"Secret number between 1-100 generated..."<<endl;
   
    do
    {
        cout<<"Please enter your guess?";
        cin>>guess;
        
        if (guess<num && guess!=0)
        {
           if(num-guess<=5)
              cout<<guess<<" is lower than the answer but close..."<<endl;
           else
              cout<<guess<<" is lower than the answer..."<<endl;
        }
        
        else if (guess>num)
        {
           if(guess-num<=5)
              cout<<guess<<" is greater than the answer but close..."<<endl;
           else
              cout<<guess<<" is greater than the answer..."<<endl;
        }
        
        else if (guess==0 || count>8)
             flag=1;
        
        else
        {
            cout<<"Correct in "<<count<<" guesses."<<endl;
            flag=1;
        }
        count++;
    }while (flag != 1);
   
    if(count>8)
       cout<<"8 guesses. The secret number is "<<num<<"."<<endl;
    else if (guess==0)
       cout<<count<<" guesses. The secret number is "<<num<<"."<<endl;
   
    return 0;
}

if  与 else if不是这么用的

如果把else if全换成 if  最后的else 也改改就对了

#include <iostream>
using namespace std;

int main ()
{
    const int num=56;

    int guess, i, flag=0, count=1;
   
    cout<<"Secret number between 1-100 generated..."<<endl;
   
    do
    {
        cout<<"Please enter your guess?";
        cin>>guess;
        
        if (guess<num && guess!=0)
        {
           if(num-guess<=5)
              cout<<guess<<" is lower than the answer but close..."<<endl;
           else
              cout<<guess<<" is lower than the answer..."<<endl;
        }
        
        else if (guess>num)
        {
           if(guess-num<=5)
              cout<<guess<<" is greater than the answer but close..."<<endl;
           else
              cout<<guess<<" is greater than the answer..."<<endl;
        }
        
        else if (guess==0 || count>8)
             flag=1;
        
        else
        {
            cout<<"Correct in "<<count<<" guesses."<<endl;
            flag=1;
        }
        count++;
        if(count>8)
        {
            cout<<"8 guesses. The secret number is "<<num<<"."<<endl;
            break;
        }
        else if (guess==0)
            cout<<count<<" guesses. The secret number is "<<num<<"."<<endl;
        }while (flag != 1);
    return 0;
}这样就好啦

#include <iostream>
using namespace std;
int main ()
{
    const int num=56;
    int guess, flag=0, count=1;
   
    cout<<"Secret number between 1-100 generated..."<<endl;
   
    do
    {
        cout<<"Please enter your guess?";
        cin>>guess;
        if (guess==num)
        {
            cout<<"Congratulations! You guess the number"<<endl;
            flag=1;
        }
        if (guess<num)
        {
           if(num-guess<=5)
              cout<<guess<<" is lower than the answer but close..."<<endl;
           else
              cout<<guess<<" is lower than the answer..."<<endl;
        }
        
        if (guess>num)
        {
           if(guess-num<=5)
              cout<<guess<<" is greater than the answer but close..."<<endl;
           else
              cout<<guess<<" is greater than the answer..."<<endl;
        }
        if (guess==0)
        {
            cout<<count<<" guesses. The secret number is "<<num<<"."<<endl;
            flag=1;
        }
        count++;
        if (count>8)
        {
            cout<<"8 guesses. The secret number is "<<num<<"."<<endl;
            flag=1;
        }
        
    }while (flag != 1);
        
    return 0;
}

count应该放在循环里

count与8大小的判断应放在循环里
