- The #include is a preprocessor command that tells the 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 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.
