Programming fundamentals — variables, data types, control flow

What you'll learn

1. 1

   Imagine a labelled box in your room — you can put different things inside and change what's in it later. That's a variable! 🧰

2. 2

   What is a variable? 🧠

3. 3

   Variables can hold different types of data: numbers (integers), text (strings), true/false (booleans). Think of them as different-shaped boxes! 📦🔢📝

4. 4

   Let's see how a variable changes in a program. 🧩

5. 5

   Now you try! Change the variable 'total' from 5 to 15 by adding 10. 🎮

6. 6

   If 'name = 'Alice'' and later 'name = 'Bob'', what happens to the old value 'Alice'? 🤔

7. 7

   A variable can store different data types. Which of these is a boolean? 🧪
