     Using your text editor, enter (i.e., type in)  the  C++
program  shown  in Display 1.8. Be certain to type the first
line exactly as shown in Display 1.8. In particular, be sure
that  the first line begins at the left-hand end of the line
with no space before or after the # symbol. Compile and  run
the  program.  If  the  compiler gives you an error message,
correct the program and recompile the program. Do this until
the compiler gives no error messages. Then run your program.

     Modify the C++ program you entered in  the  Programming
Project  1. Change the pro- gram so that it first writes the
word Hello to the screen and then goes on  to  do  the  same
things  that  the program in Display 1.8 does. You will only
have to add one line to the program  to  make  this  happen.
Recompile  the  changed program and run the changed program.
Then, change the program even more. Add one more  line  that
will  make the program write the word Good-bye to the screen
at the end of the program. Be certain to add the symbols  to
the last output statement so that it reads as fol- lows:

cout << "Good-bye\n";

(Some systems require that final  and your system may be one
of  the  systems  that requires a final 0) Recompile and run
the changed program.

     Modify the C++ program that you entered in  Programming
Project 1 or 2. Change the multiplication sign * in your C++
program to an addition sign +. Recompile and run the changed
program. Notice that the program compiles and runs perfectly
fine, but the output is  incorrect.  That  is  because  this
modification is a logic error.
