要編一個猜數字的程序 猜10次沒猜到就失敗 怎麼編
Java代碼：
public class Game{
public static void main(String[] args){
Game g = new Game();
g.gameTest(3);———–3的位置輸入你想讓別人猜得數字
}
public void gameTest(int num){
for(int count = 0 ; count 10 ; count++){
Scanner scan = new Scanner(System.in);
int in = scan.nextInt();
if(in == num){
System.out.println(“恭喜答對了！”);
break;
}
else if(count9){
System.out.println(“對不起，答錯了！您還有”+(9-count)+”次機會”);
continue;
}
else if(count == 9){
System.out.print(“遊戲失敗！”);
break;
}
}
}
}

js數組：有一個4個長度的數組，每個位置裝有0-9之間的隨機數字，有10次輸入的機會來猜每
function gameStart() {
var randomArray = getRandomArray();
var chance = 10;
while (chance–) {
var num = prompt(“請輸入一個四位數：”);
var result = judge(num, randomArray)
if (result.status == true) {
alert(“正確！遊戲結束！”);
break;
} else {
alert(“錯誤！（正確” + result.correct + “個，錯誤” + result.wrong + “個）\n你還有” + chance + “次機會！”);
}
}
}
function getRandomArray() {
var arr = []
for (var i = 0 ; i 4 ; i++) {
arr.push(parseInt(Math.random() * 10));
}
// console.log(arr);
return arr;
}
function judge(num, randomArray) {
var correct = 0;
var wrong = 0;
for (var i = 0 ; i 4 ; i++) {

correct++;
} else {

用JavaScript寫猜數字遊戲？
document.write(“input type=’text’ id=’inval’ name=’inval’/”); //數字框
document.write(“input type=’button’ onclick=’Guess();’ value=’提交'”); //按鈕
function Guess() {
var inputVal=document.getElementById(“inval”).value; //獲取文本框的值
var curRand=parseInt(100*Math.random()); //獲取隨機數
if(!isNum(inputVal))
{
alert(“不是數字，請重新輸入”);
return;
}
if(inputVal){
if(inputValcurRand){
alert(“勝利”);
} else if (inputValcurRand){
alert(“輸了”);
} else {
alert(“平局”);
}
}
}
//判斷是否是數字，true表示是數字
function isNum(value) {
return !isNaN(value);
