C programming language

The C language.....

Dialects

There are two popular dialects, the original was K&R C, which spread with the original C compiler, and pcc, the portable C compiler. Later there was a ANSI standard to the C language, and it's usually refered to as just ANSI C.

hello world

K&R

#include <stdio.h>
main(argc,argv)
int argc;
char **argv;
{
        printf("Hello World\n");
        exit (0);
}

ANSI C

#include <stdio.h>
int main(int argc, char *argv[])
{
        printf("Hello World\n");
        return 0;
}

C was derived[1] from an earlier language called B

A number of object-oriented languages have been influenced by C, including Objective-C, C++, D, Vala.
