-  ## 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.
- * 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() function 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.
+## Explanation 
+ * The `#include <stdio.h>` is a preprocessor directive. This directive tells preprocessor to include the contents of `stdio.h` (standard input and output) file in this file.
+ * 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 compiler will generate an error during compliation of 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 standard output stream, most commoly the screen. In this program, the `printf()` displays `Hello, World!` text on the screen.
+ * The `return 0;` statement is the "Exit code" of the program. In simple terms, program ends with this statement
