Computing Notes #2

Variables

• Variables could be used to store the score in a game, the number of cars in a car park or the cost of items on a till. They work in a similar way to algebra, where a letter in your code can stand for a number.
• To make a simple program that displays your name, you could program the computer to:
• 1. Ask for your name.
• 2. Store that answer as a variable called ‘YourName’.
• 3. Display “Hello” and the string stored in the variable called 'YourName'.
