java课程设计——猜数字游戏~

代码如下：
import java.util.Scanner;public class RandomT {int sum=0;public static void main(String[] args) {int number=(int)(Math.random()*100+1);int temp=number;System.out.println("请猜一个100以内的数：");RandomT rt=new RandomT();int in = rt.Sn();Boolean yn = rt.Compare(temp, in);while(!yn){System.out.println("请重新输入:");int in1 = rt.Sn();yn = rt.Compare(temp, in1);}System.out.println("正确数字是:"+number);}public Boolean Compare(int temp,int number){Boolean yesno = null;if(temp==number){if(sum==1){System.out.println("Beautiful");}else if(2temp){System.out.println("猜大了");yesno=false;}return yesno;}public int Sn(){Scanner sc = new Scanner(System.in);int in=sc.nextInt();sum+=1;return in;}}如果满意请采纳！

刚写的
import java.util.Scanner;public class Main{public static void main(String[] args) {Scanner sc = new Scanner(System.in);double dNum = 100 * Math.random();int iNum = (int) dNum, inNum, count = 0;while(true) {inNum = sc.nextInt();if(inNum == iNum) {System.out.print("猜对了.
");break;} else if(++count == 10) {System.out.print("猜测次数已达10次，猜数失败.
");break;} else if(inNum iNum) {System.out.print("输入的值大，请输入更小的数.");}}sc.close();}}

c语言编程:猜数字游戏?
答：include include <stdio.h> include <stdlib.h> define UI unsigned short int void game(){ UI answer;UI input;UI lower=1;UI upper=100;UI count=0;srand(time(NULL));do{answer=rand()%101;} while(answer==0);puts("Welcome to the number guessing game!");do { puts("Please ...

答：很简单。在JSP中是可以嵌套JAVA代码的，如 < Random r = new Random();int answer= r.nextInt(100);request.getSession.setAttribute("answer",answer);> 保存随机数到session，判断，request.getParameter("guessNumber").equals(request.getSession.getAttribute("answer"))根据结果跳转到不同的页面，...

答：//希望我的回答对你的学习有帮助#include <stdio.h>#include <stdlib.h>#include int main(){int x, magic, a = 0, c = 1;char b;do{srand(unsigned(time(NULL)));//为函数rand()设置随机数种子magic = rand() % 100 + 1;//magic为1~100间的一个数printf("您每次游戏中，只有十...

c语言编写一个猜数字游戏
答：老师要求我们用c语言编写一个程序,是一个猜数字的游戏,随机出一个数字,然后猜,可以无限制的往下猜,如果你所猜数大于随机数,会提示你too high,相反,会提示你too low。如果你猜对,游戏结束,会显示你猜了多少次,然后“1”继续玩,“0”退出 小弟刚... 展开 sunshine...

猜数字C语言
答：其实这个程序很简单，思路很清晰 首先产生一个随机的四位数，且每位都不相同 int a[10]={0,1,2,3,4,5,6,7,8,9};int b,c,i,t;for(i=0;i<100;i++) //思路就是产生两个10以内的随机数，交换a中这两个下标的数值，{ //经过多次交换后，着a中的这10个数就打乱了次序，就像...

答：include<stdio.h>#include<stdlib.h>void main(){srand(time(0));//指定随机数种子int result = rand()%1000+1;//产生1~1000的随机数int guess;//储存猜测的数字 //循环提示输入数字，直到猜测结果正确 do{printf("请输入猜测的数字\n");scanf("%d", &guess);if(guess < result){printf...

编程先由计算机“想”一个1～100之间的数请人猜,如果人猜对了,则计算机...
答：仅提供思路，自己实现比拿源码照抄好；1，设置随机数种子，一般使用当前时间， srand；2，产生随机数，rand，将产生的随机数调整到1~100之间；3，此处开始while循环;4，让人开始猜数，接收输入，判断大小，显示对应提示，如果大小相同，退出循环；end ...
