It was designed to be compiled using a relatively straightforward compiler, to provide low-level access to memory. C language is the most widely used language. There are many languages that were found after C, most of them are originated using C or with help of its features for e.g. C#, Java, PHP, Perl, Phython and many more. The extension of c program document is “.c”, so whenever you create a c program document you’ll need to save the document with this extension.
