陣列是基本的儲存有順序的元件集合的資料結構且容量是需要固定的。但可以隨機取，因為在陣列裡的每一個元素都可以透過陣列的index來標記

## Dynamic Array

### **introduce:**

&#x20;Beacuse array is need to fixed capacity and specify size when we initialize ,sometime there is inconvenient and  wasteful. therefore programing is use list&#x20;

因為陣列在初始時需要固定的大小，有時不是很方便及浪費，因此程式有使用list
