01 C Programmiersprache

1. Was ist C Programmiersprache?

C ist eine imperative und prozedurale Programmiersprache. Die Anwendungsbereiche von C sind sehr verschieden. Sie wird zur System- und Anwendungsprogrammierung eingesetzt. Die grundlegenden Programme aller Unix-Systeme und die Systemkernelvieler Betriebssysteme sind in C programmiert. Der Informatiker Dennis Ritchie entwickelte C-Sprache in den frühen 1970er Jahren an den Bell Laboratories.
