Use a for loop to solve
Program Design Exercise 17 in Chapter 4 of the text.
Solution.
-
A random number can be generated as follows. First,
create a random number generator like this:
Random randGen = new
Random();
Then if we do:
int r =
randGen.Next(10);
We will get a random number between 0 and 9, inclusive. Every time we call
randGen.Next(10) we will get a new
random number between 0 and 9. If we replace 10 with a different integer
n, then the random number generated will be between 0 and n-1, inclusive.

Use this idea, along with a few
switch statements, to write a method that generate a random sentence
every time that it is called,
that is grammatically (if not semantically) correct. Make this as fancy
as you wish. For example, you might use the sentential form
"At that moment <subject> <verb> the
<adjective> <object>" to generate sentences like
"At that moment Paul ate the green pencil",
or "At that moment Suzie loved the fast chair",
or whatever.

Create at least three kinds of sentential forms such as the
above (i.e. create at least three different methods), and then invoke them randomly to generate random paragraphs (not
unlike you see in certain kinds of email spam). For example, the output of
your overall program might generate the following different results:
Suzie loved the chair.
Then out of nowhere a dog talked to the wall. Being green, Paul then
became cold.
Being angry, Fred then
became red. Tom ate the paper. Then out of nowhere a chair barked at
the microwave.
|
Note that the problem does not require any user input, but you
may wish to add a query such as "Are you ready for another random paragraph?" to
which the user replies yes or no, thus generating a new paragraph, or not.
Have fun with this one -- show your creative side! :-)
