Learning Outcome

At the end of this lesson, you will be able to:

• understand and use select case statements

Quiz Questions

With a pencil and paper, answer the following questions:

1. Write 1 example in pseudocode of using an IF..ELSE IF..ELSE statement in daily life.

2. Write the following expressions with symbols and variables:

   • a) a negative number

   • b) a number that is 18 or greater

   • c) a number different from 0

3. Draw the flowchart for a program that does the following:

   • If the number is 3, display "The light is red"

   • Otherwise, if the number is 2, display "The light is yellow"

   • Otherwise, display, "The light is green."

4. Write 3 test cases for the above program: 1 test case for a light that is red, 1 for a light that is green and 1 for a light that is yellow.

Review

• if..then..elseif..else statements

• Here is the Problem:

  • create a "Month" program that asks the user to enter a number between 1 and 12

  • the program will then display the month that represents the number

    • for example, if the user enters 1, the program will print "<The number> is January."

  • if a number outside of the range 1..12 is entered, display "<The number> does not represent a month."
