C is a general-purpose, procedural, imperative computer programming language developed in 1972 by Dennis M. Ritchie and Brian W. Kernighan at the Bell Telephone Laboratories for use with the Unix operating system. It has since spread to every other platform, and is now one of the most widely used programming languages. It has been adapted by ISO and ANSII, and is considered a standard programming language. C has also greatly influenced many other popular languages, especially C++, which was originally designed by Bjarne Stroustroup as an enhancement to C. Due to its basic dual nature, being low-level as well as higly structured, it is the most commonly used programming language for writing system software, though it is also widely used for writing applications.
Syntax
Hello World
#include <stdio.h>
int main() {
printf("Hello, world!\n");
return 0;
}
Explanation
#include <stdio.h>tells the compiler to include the contents of the header file stdio.h, which manages standard input and output, into the program before compiling.
