<p>那么，基本数据类型与数据结构之间有什么联系呢？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”。</p>
|
||||
<p>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> 或是字符 <code>char</code> ，则与“数据结构”无关。</p>
|
||||
<p>换句话说，<strong>基本数据类型提供了数据的“内容类型”，而数据结构提供了数据的“组织方式”</strong>。例如以下代码，我们用相同的数据结构（数组）来存储与表示不同的基本数据类型，包括 <code>int</code>、<code>float</code>、<code>char</code>、<code>bool</code> 等。</p>
