C is a programming language designed for application and systems programming. It was created by the late master himself, Dennis Ritchie, so that he could create Unix. C is standardized by ISO and is currently at the C11 standard.
Qualities
C is a very simple language, whose parts can combine to form very complex code structures.
Language
C is an imperative, procedural, structured language. This means:
- Code is a sequence of statements that change program state
- Statements may be organized in control structures like
if
,while
,for
- Code may be organized as functions, which may be called from elsewhere
Type system
C is statically but weakly typed. This means:
- Types must be declared
- Values can be loosely converted between types regardless of compatibility
Examples
The examples provided here can be compiled and run using a C compiler such as gcc
or clang
.
Hello World!
#include <stdio.h> int main(void) { printf("hello, world\n"); }
