  • The stdio.h file contains functions such as scanf() and printf() to take input and display output. 
  • We Dont Use printf() function without writing #include
  • The execution of a C program starts from the main() function. 
  • printf() is a library function. In this program printf() displays "Hello World" in screen. 
  • The return 0; statement ends the program.
