Lesson 1.13 If/Else Statements

Description

In this lesson, students will take a deeper look into conditional statements, more specifically if/else statements. If/else statements allow for one thing to be done if a condition is true, and something else otherwise.

We write if/else statements like this:

if(frontIsClear()) {
    // code to execute if front is clear
} else {
    // code to execute otherwise
}

Objective

Students will be able to:

  • Explain the purpose of an If/Else statement
  • Create If/Else statements to solve new types of problems
  • Identify when an If/Else statement is appropriate to be used
