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.
