Question

Answer

**Container of objects of similar types**

An array is a fundamental data structure in computer science that is used to store a collection of elements of the same type. It is a container that allows us to store and access multiple values using a single variable name.

**Explanation:**

An array is a data structure that consists of a fixed-size sequence of elements of the same type. These elements can be of any valid data type such as integers, characters, strings, or even objects of a class. The key characteristic of an array is that it allows us to store multiple values under a single variable name.

**Example:**

Let's consider an example of an integer array:

```
int[] numbers = {1, 2, 3, 4, 5};
```

In this example, we have declared an integer array named 'numbers' that can hold five integer values. Each element in the array is accessed using its index, which starts from 0. For example, `numbers[0]` represents the first element of the array, which is 1.

**Advantages of using arrays:**

- Arrays provide a convenient way to store and access multiple values using a single variable.
- They allow efficient and direct access to elements based on their index.
- Arrays can be used to represent and manipulate data in many algorithms and data structures such as sorting and searching.
- They are widely supported by programming languages and have built-in functionality for operations like sorting, searching, and iterating over elements.

**Conclusion:**

In conclusion, an array is a container of objects or elements of similar types. It allows us to store multiple values under a single variable name and provides efficient access to elements using their index. Arrays are an essential data structure in computer science and are widely used in various algorithms and applications.

Answer

Array contains elements only of the same type.
