Imagine you have a list of students or a collection of the characteristics of the auto and you want to operate with this data in C++. It will be extremely inconvenient to store the values in single variables. To avoid such problems in C++ you can use **arrays**. The **array** is a collection of variables of the **same type** that stores multiple values. 

To declare an array you should specify the type of variables it stores, its name, and the number of elements in square brackets. For example:

Here was declared the array `students`, which consists only of `string` variables and has `5` elements. To initialize the array print the elements s a list in **curly brackets** separated by **coma**:

```
string students[5] = {"Anna", "John", "Emma", "Ross", "Barney"};
```

> The number of initialized values can be less than the number of array elements.

If you don’t know how many elements will have your array, just skip this parameter:

```
int numbers[] = {42, 12, 56, 98};
```

Each element has its position, the number of its place in the array, it is called **index**. The very first element has an index **0**, the second has an index of 1, and so on:

For example, let's get information about our array of students. You can get access to the array’s element by array’s name and the element's index in square brackets:

string students[5] = {"Anna", "John", "Emma", "Ross", "Barney"};
cout << students[3];

You can also reassign the elements of an array by its index:

string students[4] = {"Anna", "John", "Emma", "Ross"};
students[3] = "Julia";
cout << students[3];
