How Hard Is It To Learn R – From browsers to games to robotics, C++ is the programming language. But if you’re interested in learning this language, you’ve probably already heard that C++ is hard to learn. In this article, we’ll share our thoughts on how long it really takes to learn C++, and why it’s good for you to try it.
C++ evolved from the C language, a low-level cult programming language that has found many different uses. For example, both the Linux kernel and the entire Python language were written in C. The term “low-level” refers to the relative proximity of the language to the computer’s hardware. The more a language abstracts away from assembly code, the more high-level it is considered.

Bjorn Stroustrup started working on C++ back in 1979. Back then it was called “C with Classes” and sought to combine the low-level features of C with a high-level object-oriented paradigm. The successor to “C with classes” was named C++, referring to the incremental operator found in both languages (++ means “add one to hand value”).

Since then, C++ has grown into a key language for applications that use ultra-fast computing power, such as video games, autonomous driving, and the Internet of Things (IoT). The TIOBE index ranked it as the fourth most popular programming language in 2020.
So how hard is it really to learn C++? Of course, there is no universal answer. How long it takes depends on many factors, such as your experience and motivation, and what you want to do with the language. In other words, we can approach learning to code the same way we would learn to speak a new language.
Having said that, it’s true that many people personally find C++ more difficult than other languages. In some cases, it simply depends on the programming paradigm: high-level languages like Python and Java are “easier” by definition because they hide much of the complexity from the user. On the other hand, this makes them less flexible than low-level languages.

Programming in a high-level language is a bit like living in a house with lots of home assistants. You can have a nanny, cleaner and gardener. Consequently, you think less about everyday problems and can devote all your time to work and hobbies. Only when something stops working do you realize how much you trust your employees. Using low-level language, you yourself are cleaning, gardening and raising children.
Although C++ has low-level features similar to C, it also supports object-oriented programming and thus follows a high-level paradigm. Accordingly, C++ is sometimes referred to as a middle-level language. Its hybrid nature explains both C++’s strengths and its problems.
There is a rumor on the Internet that Bjarne himself rates his C++ knowledge a 7 out of 10. True or not, it shows how C++ programmers themselves struggle with the complexity of the language. Take a look at Bjarne’s FAQ where he answers questions like “How long does it take to learn C++?” and “What’s good about classes?”
The C++ syntax itself is not difficult to learn, especially if you already know C. But the versatility that makes C++ such a powerful and interesting language is itself the reason why many people find it difficult. Let’s look at some sources of confusion that can arise when learning C++.
Why R Can Be Hard To Learn
Whenever you create a new data structure (such as an integer, string, or array), it must be physically located at an address in memory. In high-level languages, we rarely think about this – the memory manager does everything for us! But in C++ we have to think about our hardware resources and how to use them most efficiently. Thus, after creating a variable and allocating space for it in memory, we must actively delete that space when we stop using the variable.
You can probably think of many ways this could go wrong. For example, if we want to use a variable that has been freed, the object will no longer exist. There is also the reverse case, where the variable continues to take up space even though the program no longer needs it. This is called a memory leak. When a program with a memory leak continues to run for a while and accumulates more and more unnecessary variables, it can crash.
This topic seems to be a source of confusion for many C++ newbies. Pointers are just variables that hold the addresses of other variables. Their big advantage is that you can work with a pointer (the address of your variable) without calling the variable itself. This makes the code faster and more efficient. And since C++ is efficiency oriented, pointers are used quite often in C++ programs. Incorrect handling of pointers can again lead to memory problems – imagine that you know the pointer, but forgot the variable, or vice versa.
As the former name C++ makes clear, the whole point of this new language was to have “C with classes”. If you come from another object-oriented language, you will have no problem understanding the concept.

Classes are schemas for complex data types called objects. They come with all kinds of attributes and features. When you instantiate a class, you are creating a new object ready with all the features. Classes provide good modular code.
We have already mentioned the compiler. A compiler is like a translator that converts the entire script into a language the computer can understand (essentially ones and zeros). There are many different compilers and you need to choose one according to your operating system. If you choose to write C++ code in an interactive development environment (IDE) such as Visual Studio or Eclipse, it will already include a C++ compiler.
If you come from a dynamically typed language like Python, you may not be familiar with this concept. Languages like C and C++ are strongly typed, which means that when you create a new variable, you declare its type—whether it’s a vector, a float, or a character—and it can’t be anything else. Python, by comparison, uses duck typing, where types are implicitly declared and can be changed at any time.
Strongly typed code has the great advantage of being somewhat self-documenting. Whereas in Python you often need to write a docstring describing what types of arguments your function accepts and what it returns, in C++ all this information is passed in the function itself.

General advice: It never hurts to learn a new programming language, especially one that works with paradigms that are new to you. This is because good programming doesn’t really require knowing a specific language inside and out.
Rather, it’s about knowing how to write clean, documented code to achieve what you want. This skill is best honed by learning more about programming in general rather than by mastering every aspect of a particular language.
But if you’re looking to dive into any of the areas we’ve mentioned (like gaming, self-driving cars, the Internet of Things, or even banking), developing a solid base in C++ will pay dividends.
You can get frustrated while learning C++ when you get to grips with topics like memory management and classes. Consider a structured learning approach to keep you motivated and speed up the process.

You may even have heard people say R is easy to learn! But ease is relative. Learning R can be challenging if you don’t know how to approach it.
If you have struggled to learn R or another programming language in the past, you are definitely not alone. And it’s not a glitch on your part or some kind of inherent language problem.
This discrepancy causes serious problems when learning any programming language, because it leads you straight to the place we like to call the boredom cliff.
How to define boring? It’s a mountain of boring programming syntax and dry practical problems that you’re usually asked to figure out before you can get to the good stuff—things you really want to do.

Nobody signs up to learn a programming language because they like the syntax. However, many learning resources, from textbooks to online courses, are written with the idea that students must master all key areas of R syntax before they can work with it.
It’s a shame so many students fall off the cliff because R is absolutely worth learning! In fact, R has some big
