Write a program that displays the word UP on the bottom line of the screen a couple of inches to the left of center and displays the word DOWN on the top line of the screen a couple of inches to the right of center. Moving about once a second, move the word UP up a line and the word DOWN down a line until UP disappears at the top of the screen and DOWN disappears at the bottom of the screen.

Then, modify the program so that after disappearing off of the screen, the word UP reappears at the bottom of the screen and the word DOWN reappears at the top of the screen. The words should continue moving until the user presses the [Enter] key to terminate the program.

Redo Programming In Previous Exercise using do. . .while loops.

The perfect-number example in this chapter uses two while loops. Rewrite the program, replacing the two while loops with two for loops and range.

To understand the value of counting loops, write a program that implements matrix multiplication using counting loop constructs. Then write the same program using only logical loops-for example, while loops.

Modify earlier exercise to combine your code from the four separate triangles of asterisks such that all four patterns print side by side.

The sum of three consecutive odd numbers is 39. What is the smaller of these numbers?

The sum of three consecutive odd numbers is $117$.

What is the smallest of the three numbers?

If you were writing the definitions for the Canine class member functions and wanted to place these in their own file, what should you name the file? ____________________

Write a program that uses a structure named MovieData to store the following information about a movie:

    Title
    Director
    Year Released
    Running time (in minutes)

Include a constructor that allows all four of these member data values to be specified at the time a MovieData variable is created. The program should create two MovieData variables and pass each one in turn to a function that displays the information about the movie in a clearly formatted manner.

A box with an open top is to be constructed from a square piece of cardboard, $3 \mathrm{~ft}$ wide, by cutting out a square from each of the four corners and bending up the sides. Find the largest volume that such a box can have. Finish solving the problem and compare the answer with your estimate in the previous part.

Consider the following problem: A box with an open top is to be constructed from a square piece of cardboard, 3 m wide, by cutting out a square from each of the four corners and bending up the sides. Find the largest volume that such a box can have. Finish solving the problem and compare the answer with your estimate in part (a).

If you were writing a class declaration for a class named Canine and wanted to place it in its own file, what should you name the file? ___________________

It is considered good programming practice to store the declaration for a class, its function definitions, and the client program that uses the class in __________________ files.

Flow control loops are usually fast compared to other loops, so they can be considered to be at steady state (essentially). In this case, integral control is recommended. Show that for $G_d=G_p=K_p$, integral control provides satisfactory control for both set-point changes and disturbances. Assume $G_v=G_m=1$
