 <p>谈及计算机中的数据，我们会想到文本、图片、视频、语音、3D 模型等各种形式。尽管这些数据的组织形式各异，但它们都由各种基本数据类型构成。</p>

 <ul>
 <li>整数类型 <code>byte</code> , <code>short</code> , <code>int</code> , <code>long</code> 。</li>
 <li>浮点数类型 <code>float</code> , <code>double</code> ，用于表示小数。</li>
 <li>字符类型 <code>char</code> ，用于表示各种语言的字母、标点符号、甚至表情符号等。</li>
 <li>布尔类型 <code>bool</code> ，用于表示“是”与“否”判断。</li>

-<p>字符的占用空间大小取决于编程语言采用的字符编码方法，详见「字符编码」章节。</p>
-<p>现代计算机 CPU 通常将 1 字节作为最小寻址内存单元。因此，即使表示布尔量仅需 1 位（<span class="arithmatex">\(0\)</span> 或 <span class="arithmatex">\(1\)</span>），它在内存中通常被存储为 1 字节。</p>

-<p>那么，基本数据类型与数据结构之间有什么联系与区别呢？我们知道，数据结构是在计算机中组织与存储数据的方式。它的主语是“结构”，而非“数据”。如果想要表示“一排数字”，我们自然会想到使用数组。这是因为数组的线性结构可以表示数字的相邻关系和顺序关系，但至于存储的内容是整数 <code>int</code> 、小数 <code>float</code> 、还是字符 <code>char</code> ，则与“数据结构”无关。</p>
