Our program is in RAM and takes some space there. Nevertheless, we still have a bunch of RAM. Imagine that it is all free, so if we need some place in the RAM, we can say to the operating system, for example, Windows: give us a little more space! 

The operating system will give or not give additional memory if there is no free place, then you will have a problem :(

Well, now we are only considering the situation when everything is fine with the RAM, there is still a lot of free space, and you can safely beg for some memory.

In such situations, you will use dynamic memory: **We do not know how much memory we need.** 

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!
