CPSC 110 Spring 2012
Quiz 3 Practice Problems
Instructions: The first three problems ask you to read a Pseudocode
function definition. Trace through each of them by hand, keeping track of the
variables, to determine the answer to the question.
- What value would functionA(5) return?
# Comment: A function definition that takes 1 argument named a
Return: a + 100
- What value would inchesToCm(10) return?
# Comment: Convert inches to centimeters
# There are 2.54 centimeters per inch
Return in * 2.54
- What value would mystery(3,2) return? What value would mystery(2,3) return?
# Comment: A mystery function with 2 arguments
To mystery(x, y):
Set M to x
If y < x then do:
Set M to y
Instructions: The next three problems ask you to define a
function in Pseudocode. Model your answers after the Pseudocode
algorithms in the first 3 questions.
- Define a function named avg3 that will compute and return
the average of any three numbers. You function should have 3 arguments
named a, b, and c.
- Define a function named kmToMiles that will convert kilometers to
miles. 1 kilometer is 0.62 miles. This function should have one argument
- Define a function named circumference that will compute the circumference
of a circle with radius r. The formula for computing circumference is
C = 2 × π × r. Use 3.14 as the value of π. This function
should have 1 argument named r.
