c

Before we study basic building blocks of the C programming language, let us look a bare minimum C program structure so that we can take it as a reference in upcoming chapters.
C Hello World Example
A C program basically consists of the following parts:
 Preprocessor Commands
 Functions
 Variables
 Statements & Expressions
 Comments
Let us look at a simple code that would print the words "Hello World":
#include <stdio.h>
int main() {    /* my first program in C */  
 printf("Hello, World! \n");      
 return 0;
 }
