Answer the questions while completing the tutorial. Pay attention to the dialogues!

1. Define what an ‘if statement’ is.

An if statement will conditionally run code depending on whether or not a condition is true.

2. Create a Variable called x and assign it to a random number between 0 and 2.

let x = randint(0, 3)

3. Write the ‘if statement’ to check if x is equal to 2. Inside the ‘if statement’, display the string “Yes”.

let x = randint(0, 3)
if (x == 2) {
    basic.showString("Yes", 150)
}

4. Write the ‘if statement’ to check if x is equal to 1. Inside the ‘if statement’, display the string “No.”

let x = randint(0, 3)
if (x == 2) {
    basic.showString("Yes", 150)
} else if (x == 1) {
    basic.showString("No", 150)
}

5. Write the code to display the string “I don’t know” if the Variable x is neither 2 nor 1.

let x = randint(0, 3)
if (x == 2) {
    basic.showString("Yes", 150)
} else if (x == 1) {
    basic.showString("No", 150)
}
else {
    basic.showString("I don't know", 150)
}
