EXERCISE SOLUTIONS
EXERCISE 1.1
O
1. List three common types of computing agents.
Solution:
FD
Human beings, desktop computers, cell phones
2. Write an algorithm that describes the second part of the process of making change (counting out the
O
coins and bills).
Solution:
C
There are various ways to do this, but here is one:
Repeat
Select the largest unit of money that is less than or equal to the remaining change Subtract this unit from
the remaining change
Until the remaining change is 0
The collection of units selected represent the change

, 3. Write an algorithm that describes a common task, such as baking a cake.
Solution:
There are various ways to do this, but here is one:
Preheat an oven to 375 degrees
Add 1 cup of water and 1 egg to a mixing bowl
Beat the liquid mixture in the bowl until the ingredients are blended Add the contents of a boxed cake mix
to the mixing bowl
Beat the mixture in the bowl until the ingredients are blended
PR
Pour the contents of the mixing bowl into a lightly greased cake pan Bake the cake in the oven for 45
minutes
4. Describe an instruction that is not well defined and thus could not be included as a step in an algorithm.
O
Give an example of such an instruction.
Solution:
FD
Attempting to divide a number by 0
5. In what sense is a laptop computer a general-purpose problem-solving machine?
O
Solution:
A laptop computer is a general-purpose problem-solving machine because it is programmable and can
C
solve any problem for which there is an algorithm.
6. List four devices that use computers and describe the information that they process. (Hint: Think of the
inputs and outputs of the devices.)
Solution:
Digital camera—images, music player—sound, cell phone—text, ATM—numbers
