設計一猜數字遊戲, 猜一介於1~99間的數字,
此數字由電腦隨機亂數產生,
使用者可重覆猜測, 且範圍會越縮越小,
最後猜中後, 計算使用者總共猜了幾次才猜中.

import java.io.Console;
public class ch34
{
public static void main(String args[])
{
Console console=System.console();
String str;
int a=1, b=99, count=0;
int ans=(int)(Math.random()*99+1);
int guess;
while(true)
{
count++;
System.out.print("猜一個"+a+"~"+b+"之間的數字: ");
guess=Integer.parseInt(console.readLine());
a=(guess<ans)?guess:a;
b=(guess>ans)?guess:b;
if(guess!=ans)
{
str=(guess>ans)?"猜得太大了":"猜得太小了";
System.out.println(str);
continue;
}
break;
}
System.out.println("恭喜你猜對了!");
System.out.println("總共猜了"+count+"次!");
}
}
