You can also allocate memory in RAM for arrays, which are called dynamic!

To create a dynamic array, just specify the type and number of elements you want in square brackets by declaring:

```
x = new int[5]; // Request memory
delete []x;    // Delete array pointed to x
```

Dynamic memory is extremely useful in many situations when your program doesn’t know how much place it needs. For instance, when your code needs to read a file or you want to create an array depending on user input.

If you want to improve your skills in C++ and already have basic knowledge of this popular programming language, then this course is for you. The next level of C++ training includes basic concepts of memory and functions in C++, defining and implementing references, pointers, and arrays. Discover standard libraries, useful topics, and dynamic memory with practical examples.

In this section, you will repeat datatypes and arrays, discovering the memory behind them.

Here you will learn what pointers and references are, where they can be used, and the difference between them.

In this section, you will explore dynamic memory features and how to apply them.

In the final section of our intermediate course, you will learn the basics of functions and then write some functions by yourself!
