#include ❮stdio.h❯   //Header File
int main()	   //Main Function
{
  printf("This is Programming Dragon");
  return 0;
}

----Output:

This is Programming Dragon

• /*...*/ will be ignored by the compiler and it has been put to add additional comments in the program. So such lines are called comments in the program

• The 2nd to 5th lines are using for documentation int he above program.

• The 8th line of the program #include <stdio.h> is a preprocessor command, which tells a C compiler to include stdio.h file before going to actual compilation.

• The 9th line int main() is the main function where the program execution begins.

• The 11th line printf(...) is another function available in C which causes the message "This is Programming Dragon" to be displayed on the screen.

• The next line return 0; terminates the main() function and returns the value 0.
