How “Hello, World!” program works?
- The
#include
is a preprocessor command that tells the compiler to include the contents ofstdio.h
(standard input and output) file in the program. - The
stdio.h
file contains functions such asscanf()
andprintf()
to take input and display output respectively. - If you use the
printf()
function without writing#include <stdio.h>
, the program will not compile. - The execution of a C program starts from the
main()
function. printf()
is a library function to send formatted output to the screen. In this program,printf()
displays Hello, World! text on the screen.- The
return 0;
statement is the “Exit status” of the program. In simple terms, the program ends with this statement.
