@ -8,7 +8,7 @@ C is an old [low level](low_level.md) structured [statically typed](static_typin
It is usually not considered an easy language to learn because of its low level nature: it requires good understanding of how a [computer](computer.md) actually works and doesn't prevent the programmer from shooting himself in the foot. Programmer is given full control (and therefore responsibility). There are things considered "tricky" which one must be aware of, such as undefined behavior of certain operators and raw pointers. This is what can discourage a lot of modern "coding monkeys" from choosing C, but it's also what inevitably allows such great performance -- undefined behavior allows the compiler to choose the most efficient implementation. On the other hand, C as a language is pretty simple without [modern](modern.md) bullshit concepts such as [OOP](oop.md), it is not as much hard to learn but rather hard to master, as any other true art.
C is said to be the **"platform independent [assembly](assembly.md)"** because of its low level nature, great performance etc. -- though C is structured (has control structures such as branches and loops) and can be used in a relatively high level manner, it is also possible to write assembly-like code that operates directly with bytes in memory through [pointers](pointer.md) without many safety mechanisms, so C is often used for writing things like hardware [drivers](driver.md). On the other hand some restrain from likening C to assembly because C compilers still perform many transformations of the code and what you write is not necessarily always what you get.

Mainstream consensus acknowledges that C is among the best languages for writing low level code and code that requires performance, such as [operating systems](operating_system.md), [drivers](driver.md) or [games](game.md). Even scientific libraries with normie-language interfaces -- e.g. various [machine learning](machine_learning.md) [Python](python.md) libraries -- usually have the performance critical core written in [C](c.md). Normies will tell you that for things outside this scope C is not a good language, with which we disagree -- [we](lrs.md) recommend using C for basically everything that's supposed to last, i.e. if you want to write a good website, you should write it in C etc.
