Edit the program

1.

Read Section 1.5 of the textbook so you understand what each line of the program does.

2.

Add a comment line to the program (anywhere) and recompile it. Run the program again. The new comment should not affect the execution of the program.

3.

Add a second print statement that prints a second message after the ``Hello, world!''. Something witty like, ``How are you?''

4.

Run the program again.
