這篇文章主要為大家詳細(xì)介紹了C++實(shí)現(xiàn)簡(jiǎn)單24點(diǎn)游戲，文中示例代碼介紹的非常詳細(xì)，具有一定的參考價(jià)值，感興趣的小伙伴們可以參考一下

本文實(shí)例為大家分享了C++實(shí)現(xiàn)簡(jiǎn)單24點(diǎn)游戲的具體代碼，供大家參考，具體內(nèi)容如下

隨機(jī)生成4個(gè)代表?yè)淇伺婆泼娴臄?shù)字字母，程序自動(dòng)列出所有可能算出24的表達(dá)式，用擅長(zhǎng)的語(yǔ)言（C/C++/Java或其他均可）實(shí)現(xiàn)程序解決問(wèn)題。

程序風(fēng)格良好(使用自定義注釋模板)

列出表達(dá)式無(wú)重復(fù)。

以下為源代碼

#include<iostream>
#include<string>
#include <stdlib.h> 
#include<time.h>
using namespace std;

char ope[4] = { '+','-','*','/' };
 
 
void cre()//生成
{
 int i = 0;
 int j;
 cout << "生成的四張牌面為：";
 srand((unsigned)time(0));
 for (i = 0; i<4; i++)
 {
 j =rand() % 13;
 buf[i] = card[j];
 }
