Unit3-08: Nested If Statements

Learning Outcome

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

• A2.3 write algorithms with nested structures (e.g., to count elements in an array, calculate a total, find highest or lowest value, or perform a linear search). 

• understand and use nested if statements

Quiz Questions

With a pencil and paper, answer the following questions:

1. Write an example in daily life that uses each of the following logic operators, written in everyday language:

   • a) AND

   • b) OR

   • c) NOT

2. Use the compound operators (not, and, or) to create a pseudocode for the following program:

   • Ask the user for the day of the week (i.e. Monday, Tuesday, etc.)

   • If it is not Saturday or Sunday, tell them they have to go to school. Otherwise, tell them they can sleep in!

3. Write 2 test cases for the above program (1 test case for a weekday, 1 test case for a weekend).

4. ICS3U Only: What would happen if the seed (outlined in red) was not created? What is the purpose of creating a seed for random number generators?

Review

• compound boolean expressions

Here it the Problem:

• Read "What is a Leap Year?" to determine what is a "leap" year.

• Create a program that will ask the user to enter a year and then tell the user if it is a "leap" year. 

• Use the % (modulo) operator to find the remainder when dividing.

• Make sure to "catch" any invalid entries so that your program does not crash.
