The C programming language was invented in the early 1970s, and since then has become one of the most popular and widely used general-purpose languages. It’s used by a wide range of programmers, from amateurs working on simple projects at home, to industry professionals who write in C for a living. It’s been used to program everything from the tiny microcontrollers used in watches and toasters up to huge software systems – most of Linux (and Raspberry Pi OS itself) is written in it. It can give you control over the smallest details of how a processor operates, but is still simple to learn and read.
C is a very powerful language – there’s not much you can’t use it for – but it’s fairly simple. The language itself only has 20 or so keywords, but there’s a huge library of additional functions that you can call in when you need them.
