Why Programs Need Decisions and Repetition
Imagine you are deciding what to wear in the morning. If it is raining, you choose a raincoat. If it is sunny, pick a T-shirt. This decision is based on the weather. After making your choice, you might brush your teeth, eat breakfast, and pack your bag, actions you repeat every day. Programs work similarly. They make decisions and repeat actions, allowing them to solve problems and handle many situations automatically.

The code above shows how a computer can make a choice—telling you to take an umbrella if it is rainy—and how it can repeat an action, such as reminding you to brush your teeth for three days in a row. This mirrors the way you make decisions and follow routines in your daily life.
