   ## Explanation 
+  
  * 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 `printf()` to take input and display output respectively.
  * If you use `printf()` function without writing `#include <stdio.h>`, the program will not be compiled.
+ * Two backslash characters (//) are used to _comment_ the code, for better understandability. Anything after // on a line is ignored while compiling the program.
  * 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 `\n` in `printf` creates a new line for the forthcoming text. 
  * The `return 0;` statement is the "Exit status" of the program. In simple terms, program ends with this statement

  ## Output:
  ```
  >Hello World!
  ```

  #### More Information
  
  * Conventionally, the first ever program you write is the "hello world" program, be it in any language.
