Probably the first line of text that everyone prints out on the console when one begins his/her remarkable jouney of this endless programming world.

## Explanation
|
||||
* The #include <stdio.h> is a preprocessor command. This command tells compiler to include the contents of stdio.h (standard input and output) file in the program.
|
||||
* The stdio.h file contains functions such as scanf() and printf() to take input and display output respectively.
|
||||
* If you use printf() function without writing #include <stdio.h>, the program will not be compiled.
|
||||
* The execution of a C program starts from the main() function.
|
||||
* The printf() is a library function to send formatted output to the screen. In this program, the printf() displays `Hello, World!` text on the screen.
|
||||
* The \n in printf creates a new line for the forthcoming text.
|
||||
* The return 0; statement is the "Exit status" of the program. In simple terms, program ends with this statement
