Programming tutorial for c. Video course content
Learning the C++ programming language. In this course, we will learn C++ from scratch. Lessons for beginners and knowledgeable in this language. We will go through all the steps from simple variables to complex applications of OOP (Object Oriented Programming)
Video lesson:
Useful links:The C++ language appeared back in 1983. It is based on the C language, but featured new features that greatly simplified the creation of applications and introduced many new concepts such as: OOP (creating classes and objects), inheritance, freeing and deleting memory (new and delete), virtual functions, exceptions, and many other innovations.
Language C++ got its name from the C language, but with the addition of ++ , as it means increment (increment by one). Thus, it inherits all the principles of the classical C language, but with new very useful additions.

Many people advise you to learn C first before C++, but you really shouldn't. If you start learning C++ right away, you will gain knowledge from a newer language and switching to an older language will not be difficult at all. And it is not known whether it will be necessary to make a transition to an older language at all, most likely not.

Homework for the video lesson
What is C++?What is C++ used for and what functions can it perform?
View answer
C++ is a cross-platform programming language that is used to build applications, websites, games, and many other things. Due to its early appearance, it has been used in many areas related to programming.
Bochum's contribution to the teaching of foreign languages in research and teaching. In this article, we will try to answer the most common questions that will help you better compare languages and make learning decisions. Well, as always, the answer depends on many factors, but mainly on what kind of events you plan to perform in the future.
What is easier to know?
The reason is that by not having the old applications to support you, you have the luxury of only working with the new language, not counting the legacy code. If you are going to work for a company, it is almost mandatory that you learn both languages. Also, even if your new company starts from scratch, it's more than likely that you won't stay with it for the rest of your life, and the next one will most likely have a legacy code. Today it is still difficult. There is often a confusion here of two concepts that have nothing in common: one thing is that Swift is easier to write and read, and the other is completely different, which is easier to learn.
Stephan R. Davies “C++ for Dummies” Dialectics, 2007, 384 pages, 5th edition, (18.6 mb. pdf)
For dummies, literally “beginner's guide to the C++ programming language”. The main difference between the 5th edition and the previous ones is that it is really designed for beginners who are not familiar with programming. In previous editions, the reader was required to have a basic knowledge of the C language. from the basics of the C ++ language, the concept of the language paradigm and the study of syntax.
For example, anything related to additional meanings and usage? and! to indicate your intentions. This may sound bad and makes learning difficult, but it really isn't. And it's harder to learn. It can be easily seen with real example: matrices. In the first case, an error will occur if you try to change the matrix, and in the second case, the intent will be cleared from the name, so it's much simpler and less error prone. But that doesn't mean it's harder to learn, but it could only mean the opposite.
Therefore, if this part is covered, you just need to learn the language. And you can use almost everything you already know. Yes Yes; in both cases, which reinforces the thesis that it is good to know two languages. While it is true that some of these questions are somewhat esoteric and will not matter in Everyday life, it is always recommended to use a wider range of tools.
The book consists of 6 parts, but thematically it can be divided into three: the introductory part, as already mentioned - introductory, the second - functional programming, as the basis for OOP and the third - object-oriented programming (which actually differs from C and what is its strength ). Despite the fact that the C ++ language cannot be called simple, the material in the book is quite accessible and quite informative.
From the outset, as can be deduced from the foregoing, it would be desirable that you study both. Safer to develop as it hides more complexity and manages memory automatically. Testing is easier thanks to playgrounds.
- It is easier to write and read, and the code is more concise.
- It's easier to maintain.
- Your applications will run faster.
Learning a foreign language while you sleep: what does the science say?
There are a number of misconceptions about learning foreign languages. These include the ability to learn foreign languages through sleep or hypnosis. Various studies have been carried out on the activity of the brain during sleep, as well as its ability to learn during this period of rest, which is necessary for each person. Focus on the results of two of them.
The author made a teaching emphasis on the questions - “why” and “how” in general, certain language constructions work. The book provides many concrete examples, both in a few lines of code, and the code of fully completed working programs. If you put the effort and perseverance into studying this initial guide, then it is quite possible that by the end of studying the book you will be able to write intelligible (understandable to you - why and how they work) programs.
Memory and sleep: what the brain can do
If we believe in science, the brain will not completely stop during sleep and will even be able to hold everything. After several nights in a row listening to the noises, the subjects remembered the noise and were able to recognize it when they woke up. These results, even if they are associated with meaningless noises, nevertheless remain interesting for the future, because they show that the brain is able to record information during sleep. This study focused on learning Dutch from 60 German speakers.
If so, then you can proceed to the study of more “advanced” literature. The book will be of interest to students who begin to learn programming in C ++ and for independent initial learning.

The study was carried out as follows. The students had to memorize pairs of vocabulary words starting at 22:00. Then part of the group fell asleep while listening to the recording of the words, which were to be held at a moderate level, while the other side had to watch and listen to the vocabulary. Sleeping subjects woke up after 3 hours and had better results than the other group during the vocabulary restitution phase. Sleep, if not used in this case to learn something new, has played a significant role in vocabulary memorization.
Considering the results of these various studies, it is clear that the brain is capable of acquiring freshly learned vocabulary and simple unknown cues during sleep. However, it has not yet been established that the brain is capable of learning all of language and its intricacies during sleep. Nothing now replaces active learning for effective promotion.

Sleep is very important for students
Although on this moment seems difficult to study foreign language while sleeping, we still remember that sleep plays a role in the success of this business. A good night's sleep is indeed essential to a person's well-being because it allows the body to recharge and regenerate.
Lack of prolonged sleep has harmful consequences for a person. In addition to being drowsy, lack of sleep has an effect. Perception of our environment; Reaction time; Mood; Concentration ability Weight; Memory; Concentrations. Among these various consequences, memory and concentration problems will undoubtedly be the most detrimental to people learning foreign languages. They are likely to delay their progress, not to mention that latent irritability can affect the student's enthusiasm and motivation.

Learn a foreign language with hypnosis
In short, heal your sleep! Most of the time, they are hypnotherapists who offer one-on-one or distance learning programs via video or audio recordings. During these classes, students will Immersed in a state of relaxation that will promote their concentration and receptivity when the teacher will repeat the words and phrases to remember. Awakens to restore the dictated elements facing the teacher. After immersing yourself in the state of hypnosis, repeat again the elements learned with the teacher. The results of this method seem to differ from one person to another.

It seems that the brain is indeed able to assimilate sentences and vocabulary during hypnosis sessions, but in a limited way. Theoretically, according to experts in this discipline, it will take 40 hours of hypnosis to master the language. Note, however, that even if the student succeeds in memorizing sentences and understanding them, theoretical aspect will always be absent. Indeed, language lessons under hypnosis focus only on the spoken language. All the rules of grammar, syntax and spelling are thrown into the background, and the student will have to take an active interest in himself if he wants to improve his command over the language.

It is important to remember that it is still impossible to learn a foreign language during sleep, even if the brain seems to be able to store information during the light and REM sleep phases. Lateral hypnosis, this is less easy to solve. Students appear to be able to retain vocabulary and sentences during sessions, but in a limited way. They find themselves quickly deprived when they have to face difficulties in speaking.
It is even better to rely on tried and tested methods such as language methods such as assimilation or language institute courses. To progress quickly and efficiently, there is no secret or miracle method: only regularity and regularity pays in the long run.

The official documentation is very educational. We start with proper consideration: a hacker is seen as someone who commits cybercrime, but it is not, a hacker is much more than that. The concept of hacking should be understood as a discipline for learning new things and solving even difficult problems. So, how to become a hacker from scratch, from nothing? Today we will explain exactly how to pursue this profession and how to become a professional hacker. Of course, after reading this article, you cannot claim to be a hacker, but you can enter the world of hacking and, starting from the basics, aim to become a hacker.Chapter 8 Getting Started with Pointers in C++ 105
