Use this activity document to guide your work in the [magic 8 tutorial](/microbit/lessons/magic-8/tutorial).
|
|
|
|
Answer the questions while completing the tutorial. Pay attention to the dialogues!
|
|
|
|
## 1. Define what an 'if statement' is.
|
|
|
|
<br />
|
|
|
|
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.
|
|
|
|
```blocks
|
|
let x = Math.random(3)
|
|
```
|
|
|
|
## 3. Write the 'if statement' to check if ``x`` is equal to 2. Inside the 'if statement', display the string "Yes".
|
|
|
|
```blocks
|
|
let x = Math.random(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."
|
|
|
|
```blocks
|
|
let x = Math.random(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.
|
|
|
|
```blocks
|
|
let x = Math.random(3)
|
|
if (x == 2) {
|
|
basic.showString("Yes", 150)
|
|
} else if (x == 1) {
|
|
basic.showString("No", 150)
|
|
}
|
|
else {
|
|
basic.showString("I don't know", 150)
|
|
}
|
|
```
