## Exploring the best resources available online to learn C++ for free in 2023.

Every now and again I get asked the question: _should I learn C++?_

Now, as with any programming language, there are many pros and cons to learning C++.

Therefore, I will always be an advocate for learning _any_ language you want to. As long as you’re willing to put in the **time and effort** required, then there should be nothing stopping you!

If you haven’t quite made your mind up about learning C++, read on to find out a bit more about it:

## What is C++?

C++ is one of the most widely used programming languages in the world, powering everything from operating systems to video games.

> But where did it come from?

C++ was [originally created](https://en.wikipedia.org/wiki/C%2B%2B) in the early 1980s as an extension of the C programming language at Bell Labs by [Bjarne Stroustrup](https://en.wikipedia.org/wiki/Bjarne_Stroustrup).

The aim was to add object-oriented programming (OOP) features to the procedural C language. The first commercial implementation was released in 1985.

Over time, C++ has evolved enormously, going through several standard revisions that have added many major features - like templates, exceptions, references, and the STL standard library.

The latest C++ standard is [C++20](https://en.cppreference.com/w/cpp/20), ratified in 2020, which introduces concepts, modules and ranges among other improvements.

## Why Learn C++?

So why should you consider learning C++ as a programming language?

Here are some key advantages of C++:

- **Speed and Efficiency** - C++ is compiled directly into native machine code, making it extremely fast and efficient for tasks like game development, high-frequency trading, and other performance-critical applications.
- **Versatility** - C++ supports procedural, object-oriented and generic programming paradigms. This flexibility allows C++ to be used for developing desktop apps, device drivers, embedded firmware, high-performance servers, and even [Android apps](https://dev.to/evergrowingdev/learn-how-to-build-android-apps-with-these-7-free-resources-1na6).
- **Systems Programming** - C++ is widely used for developing operating systems, databases, compilers and other system software where access to low-level hardware control is needed.
- **Large Developer Community** - C++ has existed for decades and has one of the largest developer communities worldwide. There is abundant code, documentation, tools, and libraries to leverage.
- **In-Demand Skill** - There is great industry demand for C++ developers, especially in fields like finance, game engines, robotics, drivers, and graphics. Learning C++ can open up lucrative career opportunities.

## Pros and Cons of Learning C++

Some pros of C++ include:

- Memory access control and low-level manipulations
- Speed and performance closer to hardware
- Ability to use procedural or OOP approach
- Strong static type checking and type safety

Potential downsides to consider:

- Complex syntax with lots of keywords and concepts
- Manual memory management can lead to errors
- Steep learning curve for beginners compared to languages like [Python](https://dev.to/evergrowingdev/become-a-python-pro-for-free-with-these-9-resources-4c8c)
- Larger executable file sizes due to compilation

As you can see, with both strengths and weaknesses, C++ is an extremely powerful language perfect for certain applications.

Though it may not be the best choice for everything - but no language is - it’s still very relevant and popular today.

If you’re sold on learning C++, the good news is there are many free-to-use online resources available for you to learn it.
