Step 1: Understand what an array is. An array is a collection of items stored at contiguous memory locations.
Step 2: Learn about the size of an array. When you create an array, you must specify how many items it can hold.
Step 3: Recognize the limitation of fixed size. Once the size is set, you cannot change it. This means you cannot add more items than the size allows.
Step 4: Compare with linked lists. Unlike arrays, linked lists can grow and shrink in size because they are made of nodes that can be added or removed.
Step 5: Conclude that the main disadvantage of arrays is their fixed size, which makes them less flexible than linked lists.
