“猜数字“游戏，系统随机生成一个[1,100]的数字，由用户输入数字后，计算机提示输入数字“偏大”、“偏小”，并记录猜数次数

import java.util.Scanner;

public class Demo {

	public static void main(String[] args) {
		// TODO Auto-generated method stub
		Scanner in = new Scanner(System.in);
		int number = (int) (Math.random()*100+1);
		//(0,1)*100=(0,100)+1=[1,100] 
		int count = 0;
		int a;
		do {
			a = in.nextInt();
			if(a>number)
			{
				System.out.println("偏大");
			}
			else if (a<number)
			{
				System.out.println("偏小");
			}
			count++;
		}while(a!=number);
		
		System.out.println("恭喜你猜对了，你猜了"+count+"次");

	}
