逻辑错误 指点下

[kukuyouhuo]

#include<iostream>
using std::cin;
using std::cout;
using std::endl;
#include<cstdlib>
#include<ctime>
#include<string>
int display();

int main()
{int a,b;
int x;
srand(time(0));
cout<<"i have a number between 1 and 1000"<<endl;
cout<<"can you guess my number?"<<endl;
cout<<"please type your first guess:";

while(a=display())
{cin>>b;

if(b==a)
{ cout<<"Excellent!you guess the number"<<endl;
cout<<"would you like to play again(y or n)?";
cin>>x;
if(x==1)
continue;
else
break;}

while(b!=a)
{if(b>a)
{cout<<"too high try again:";
cin>>b;}
if(b<a)
{cout<<"too low try again:";
cin>>b;}
}

}
system("pause");
return 0;
}
int display()
{ return 1+rand()%999;}


这个语句块实现不了 大家帮忙改进下 谢谢

换一下位置就可以了

while(a=display()) 
{cin>>b; 
      while(b!=a) 
       {if(b>a) 
           {cout < <"too high try again:"; 
           cin>>b;} 
        if(b <a) 
           {cout < <"too low try again:"; 
           cin>>b;} 
         }   

       cout < <"Excellent!you guess the number" < <endl; 
        cout < <"would you like to play again(y or n)?"; 
        cin>>x; 
        if(x==1) 
        continue; 
        else 
        break; 
       
   
     
 }
