終極密碼 in C++

#include <iostream>
#include <cstdlib>
#include <ctime>
using namespace std;
/* run this program using the console pauser or add your own getch, system("pause") or input loop */

int main(int argc, char** argv) {

int input;
int password;
int low=1,high=100;                    //設定亂數範圍
srand((unsigned)time(NULL));   //以時間做為亂數種子
password=rand()%high+low;     
    cout<<"Please enter number between 1~100"<<endl;
while(cin>>input){
if(input<password){
cout<<"Larger!"<<endl;
low=input;
cout<<"Please enter number between"<<low<<"~"<<high<<endl;}
if(input>password){
cout<<"Smaller!"<<endl;
high=input;
cout<<"Please enter number between"<<low<<"~"<<high<<endl;}
if(input==password){
cout<<"NiceWork!";
break;}
}
return 0;
}

使用較為直觀的方法寫成
