<title>对于动,静态数组使用的一些小思考</title>

<p>这次C++练手项目是一个通讯录管理系统，跟着以上B站视频教程（P72-P83）进行开发。<br>但是，这一次练习解答和我大作业的解答格外相似，但是我用的是vector数组，我立马拿去和上一次大作业的对比，<br>这引发了我思考——<em><strong>vector动态数组</strong></em>和<em><strong>静态数组</strong></em>到底该如何做选择？<br>通过这次练习，这个问题得到解答。<br>如果想查看之前大作业的代码，可以翻阅之前发布的博客文章。</p>
<p>以下是代码</p>

<p>静态数组和vector动态数组各有千秋：</p>
<p> <strong>Vector动态数组：</strong></p>
<ol>
<li><p><strong>动态大小</strong>：Vector 是一个动态容器，可以根据需要在运行时调整大小。它能够自动处理内存管理和扩展，而无需显式指定初始大小（与静态数组不同）。这使得 Vector 更加灵活，能够适应动态的数据需求。</p>
</li>
<li><p><strong>安全性</strong>：Vector 具有边界检查功能，可以确保访问元素时不会越界，减少了程序崩溃或发生其他错误的风险。而静态数组没有内置的边界检查机制，如果不小心越界访问，可能会导致未定义的行为。</p>
</li>
<li><p><strong>方便的操作和函数</strong>：Vector 对象提供了方便的成员函数和算法，如插入、删除、排序等操作。而静态数组通常需要手动编写这些操作的代码，相对来说更加繁琐。</p>
</li>
<li><p><strong>可以返回长度</strong>：Vector 有 <code>size()</code> 成员函数用于获取当前容器中元素的数量，而对于静态数组，需要使用额外变量或固定长度进行追踪。</p>
</li>
<li><p><strong>可以作为函数参数和返回值</strong>：Vector 可以直接作为函数的参数和返回值传递，而静态数组传递时需要指定数组大小，且容易造成内存浪费或限制传递的数组大小。</p>
</li>
</ol>
<p> <strong>静态数组：</strong></p>
<ol>
<li><strong>内存效率</strong>：静态数组在编译时就分配了连续的内存空间，并且没有额外的运行时开销。这使得静态数组在内存访问方面更加紧凑和高效，能够提高数据访问的局部性和缓存命中率，从而提升访问性能。</li>
<li><strong>简单和直观</strong>：静态数组是一种基本的数据结构，使用起来非常简单和直观。只需声明数组并指定大小，即可直接访问和操作数组元素。</li>
<li><strong>编译时确定大小</strong>：静态数组的大小在编译时确定，无法动态改变。这可以作为一种约束，确保不会超出预期的数组范围，并在编译时发现潜在的错误。</li>
<li><strong>不涉及动态内存管理</strong>：由于静态数组在编译时分配了固定大小的内存，因此不存在动态内存管理的问题。这样可以避免动态内存分配和释放带来的开销和内存碎片问题。</li>
<li><strong>适用于小规模数据集</strong>：对于小规模的数据集，静态数组的性能优势通常是微不足道的。与 Vector 数组相比，静态数组可能具有更低的内存开销和更高的执行效率。</li>
</ol>
<p>在选择使用静态数组还是 Vector 数组时，需要综合考虑具体场景、数据规模和操作需求，并权衡各自的优缺点。</p>

<p>卧槽，刚才让chatGPT写我的C++大作业。代码写的比我好几百倍 ，代码原本是用结构体，我把结构体换成类再作修改就符合题目要求，且使用效果更好。代码写的比我好几百倍，看的我人都傻了，让我大受震撼。主要是代码里对vector和Range-based for loop的使用能够大大简化代码（相对于我写的）。简化内存管理、提高代码效率、提供高效的插入和删除操作，并且易于使用和理解。</p>

<title>部署博客后打开网站显示404</title>
<url>/2024/09/16/Hexo%E9%83%A8%E7%BD%B2%E9%97%AE%E9%A2%98/</url>
<content><![CDATA[<p>我把Node.js更新到v22.8.0，接着更新了Hexo，</p>
<p>最后我部署完后发现博客404了，但是hexo s 正常显示，于是我认为是部署出了问题，</p>
<p>所以检查了博客根目录下的**.deploy_git<strong>文件夹，</strong>发现里面没有任何东西**。</p>
<p>首先，我用taobao源重新安装了hexo-deployer-git</p>
<div class="highlight-container" data-rel="Plaintext"><figure class="iseeu highlight plaintext"><table><tr><td class="code"><pre><span class="line">cnpm un hexo-deployer-git</span><br><span class="line">cnpm i hexojs/hexo-deployer-git</span><br></pre></td></tr></table></figure></div>
<p>然后：</p>
<div class="highlight-container" data-rel="Plaintext"><figure class="iseeu highlight plaintext"><table><tr><td class="code"><pre><span class="line">Hexo clean</span><br><span class="line">hexo g </span><br><span class="line">hexo d</span><br></pre></td></tr></table></figure></div>
<p>打开博客发现无济于事。</p>
<hr>
<p>正当我焦头烂额时， 在无意间瞥到了终端的这张图，加上先前看到的下面这个相关问题的帖子，发觉到可能是Node.js版本过新</p>
<p><img
lazyload
src="/images/loading.svg"
data-src="https://gcore.jsdelivr.net/gh/Anivia-ad/photo_DEMO/img/2024_09_16_22.8.0.png"
></p>
<p>帖子： <a class="link" href="https://blog.csdn.net/qq_45865697/article/details/121892998" >https://blog.csdn.net/qq_45865697/article/details/121892998</a></p>
<p>我去看了眼hexo-deployer-git 最新版的发布日期，发现是2023年2月6号，基本确定原因是<em><strong>Node.js版本过新</strong></em></p>
<p>于是把node.js换成v20.17.0 (LTS) 版本</p>
<p><img
lazyload
src="/images/loading.svg"
data-src="https://gcore.jsdelivr.net/gh/Anivia-ad/photo_DEMO/img/2024_09_16_v20.17.0_node.png"
></p>
<p>重新部署网址，成功解决！</p>
<p>这次给了我一个教训：<strong>不要随便更新Node.js！</strong></p>
<p>下面的帖子也是和我一样的情况：</p>
<p><a class="link" href="https://ten-z.github.io/2022/03/17/Hexo-Github%E5%8D%9A%E5%AE%A2%E7%A7%BB%E6%A4%8D%E5%8F%8A%E7%99%BD%E5%B1%8F%E9%97%AE%E9%A2%98/" >https://ten-z.github.io/2022/03/17/Hexo-Github%E5%8D%9A%E5%AE%A2%E7%A7%BB%E6%A4%8D%E5%8F%8A%E7%99%BD%E5%B1%8F%E9%97%AE%E9%A2%98/</a></p>
<p>下面有其他的Hexo部署插件：</p>

<p>更新Hexo:</p>
<div class="highlight-container" data-rel="Plaintext"><figure class="iseeu highlight plaintext"><table><tr><td class="code"><pre><span class="line"># 使用淘宝源的 cnpm 替换 npm</span><br><span class="line">npm install -g cnpm --registry=https://registry.npm.taobao.org</span><br><span class="line"></span><br><span class="line">cnpm install -g cnpm # 升级 npm</span><br><span class="line">cnpm cache clean -f # 清除 npm 缓存</span><br><span class="line"></span><br><span class="line">===更新 hexo: 进入 blog 目录，执行如下命令=== </span><br><span class="line"># 更新 package.json 中的 hexo 及个插件版本</span><br><span class="line">cnpm install -g npm-check # 检查之前安装的插件，都有哪些是可以升级的 </span><br><span class="line">cnpm install -g npm-upgrade # 升级系统中的插件</span><br><span class="line">npm-check</span><br><span class="line">npm-upgrade</span><br><span class="line"></span><br><span class="line"># 更新 hexo 及所有插件</span><br><span class="line">cnpm update</span><br><span class="line"></span><br><span class="line"># 确认 hexo 已经更新</span><br><span class="line">hexo -v</span><br></pre></td></tr></table></figure></div>

<title>C++鼠标连点器</title>

<content><![CDATA[<p>前几天LOL PBE 出现了BUG，可以无限刷宝箱。但是要鼠标连续4下才能刷到。于是我就想到用鼠标连点器来自动刷。<br><img

<p>经过几次搜索，我在知乎上找到了能够自己设定鼠标坐标的连点器，我稍微修改了一下。</p>
<p>最后，我也成功刷了1W多个宝箱。</p>

<p><a class="link" href="https://www.bilibili.com/read/cv5107169" >GitHub 账号注册详细流程</a></p>
<p>2.下载 Node.js 和 npm 软件(npm 包含其 node.js 里)。</p>
<p><a class="link" href="https://nodejs.org/en/" >Node.js 官网</a> </p>
<p><strong>注意！版本尽量选LTS，防止后面无法部署。</strong></p>
<p>3.下载 Git 软件。</p>

<content><![CDATA[<p>因为个人原因很久没更新博客，前几天想着更新我的博客，写好后拿去Hexo s ，结果报错 。下面是报错结果：</p>

<h1 id="思路一"><a href="#思路一" class="headerlink" title="思路一"></a>思路一</h1><p>因为很久没更新 ，我第一时间想到的是不是因为node.js 和npm版本太老了？于是就更新了node.js 和npm。</p>
<p>node.js更新我是去官网下载最新版安装包 。</p>
<p>而npm更新则是用命令行更新。</p>
<p>NPM更新到最新版命令：</p>
<div class="highlight-container" data-rel="Plaintext"><figure class="iseeu highlight plaintext"><table><tr><td class="code"><pre><span class="line">npm install -g npm</span><br></pre></td></tr></table></figure></div>
<h1 id="思路二"><a href="#思路二" class="headerlink" title="思路二"></a>思路二</h1><p>现在电脑上的node.js 和npm均是最新版了，但是hexo s后仍然报错，还是同样的ERROR，但是看到别人却成功了。于是分析了一下报错信息，</p>
<p>发现了这几行东西：</p>
<div class="highlight-container" data-rel="Plaintext"><figure class="iseeu highlight plaintext"><table><tr><td class="code"><pre><span class="line">ERROR Plugin load failed: hexo-butterfly-clock</span><br><span class="line">Error: ENOENT: no such file or directory, open 'D:\blog\node_modules\hexo-butterfly-clock' </span><br><span class="line">ERROR Plugin load failed: hexo-wordcount</span><br><span class="line">Error: ENOENT: no such file or directory, open 'D:\blog\node_modules\hexo-wordcount'</span><br></pre></td></tr></table></figure></div>
<p>就发现<strong>根本原因是hexo-butterfly-clock和hexo-wordcount这2个插件缺失</strong></p>
<p>于是就立马下载插件</p>
<h2 id="安装hexo-butterfly-clock"><a href="#安装hexo-butterfly-clock" class="headerlink" title="安装hexo-butterfly-clock"></a>安装hexo-butterfly-clock</h2><div class="highlight-container" data-rel="Plaintext"><figure class="iseeu highlight plaintext"><table><tr><td class="code"><pre><span class="line">npm install hexo-butterfly-clock --save </span><br></pre></td></tr></table></figure></div>
<p>或者</p>
<div class="highlight-container" data-rel="Plaintext"><figure class="iseeu highlight plaintext"><table><tr><td class="code"><pre><span class="line">cnpm install hexo-butterfly-clock --save</span><br></pre></td></tr></table></figure></div>
<h2 id="安装hexo-wordcount"><a href="#安装hexo-wordcount" class="headerlink" title="安装hexo-wordcount"></a>安装hexo-wordcount</h2><div class="highlight-container" data-rel="Plaintext"><figure class="iseeu highlight plaintext"><table><tr><td class="code"><pre><span class="line">npm install hexo-wordcount --save</span><br></pre></td></tr></table></figure></div>
<p>或者</p>
<div class="highlight-container" data-rel="Plaintext"><figure class="iseeu highlight plaintext"><table><tr><td class="code"><pre><span class="line">cnpm install hexo-wordcount --save</span><br></pre></td></tr></table></figure></div>
<p>到此，再次hexo s ，可发现问题已解决。</p>
