3. Update the program in Listing 2.1 by adding one more newline character into the message printed out by the printf() function. You should see two lines of the message on the screen after running the updated executable file:
Howdy, neighbor!
This is my first C program.
4. What warning or error messages will you get when you're trying to compile the following program?
#include <stdlib.h>
