  • 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 print() 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 return 0; statement is the "Exit status" of the program. In simple terms, program ends with this statement.
