• The #include 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 print() to take input and display output respectively.

• If you use printf() function without writing #include , 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 return 0; statement is the "Exit status" of the program. In simple terms, program ends with this statement.
