-C is an [old](old.md) [low level](low_level.md) structured [statically typed](static_typing.md) [imperative](imperative.md) compiled [programming language](programming_language.md), it is very fast and currently mostly used by [less retarded software](lrs.md). Though by very strict standards it would still be considered [bloated](bloat.md), compared to any mainstream [modern](modern.md) language it is very bullshitless, [KISS](kiss.md) and greatly established and "culturally stable", so it is also the go-to language of the [suckless](suckless.md) community as well as most true experts, for example the [Linux](linux.md) and [OpenBSD](openbsd.md) developers, because of its good, relatively simple design, **uncontested performance**, **wide support**, great number of compilers, level of control and a greatly established and tested status. C is **perhaps the most important language in history**; it influenced, to smaller or greater degree, basically all of the widely used languages today such as [C++](c.md), [Java](java.md), [JavaScript](javascript.md) etc., however it is not a thing of the past -- in the area of low level programming C is still the number one unsurpassed language. C is by no means perfect but it is currently probably the best choice of a programming language (along with [comun](comun.md), of course).

 Some of the typical traits of C include great reliance on and utilization of **[preprocessor](preprocessor.md)** ([macros](macro.md), the underlying C code is infamously littered with "`#ifdefs`" all over the place which modify the code just before compiling -- this is mostly used for compile-time configuration and/or achieving better performance and/or for [portability](portability.md)), **[pointers](pointer.md)** (direct access to memory, used e.g. for memory allocation, this is infamously related to "shooting oneself in the foot", e.g. by getting [memory leaks](memory_leak.md)) and a lot of **[undefined behavior](undefined_behavior.md)** (many things are purposefully left undefined in C to allow compilers to generate greatly efficient code, but this sometimes lead to weird [bugs](bug.md) or a program working on one machine but not another, so C requires some knowledge of its specification). You can also infamously meet complicated type declarations like `void (*float(int,void (*n)(int)))(int)`, these are frequently a subject of [jokes](jokes.md) ("look, C is simple").

+Unlike many "[modern](modern.md)" languages, C by itself doesn't offer too much advanced functionality such as displaying graphics, working with network, getting keyboard state and so on -- the base language doesn't even have any [input/output](io.md), it's a pure processor of values in memory. The standard library offers things like basic I/O with standard input/output streams, basic operations with [files](file.md), strings, time, math functions and other things, but for anything more advanced you will need an external library like [SDL](sdl.md) or [Posix](posix.md) libraries.
 
 C is said to be a **"[portable](portability.md) [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.
