If-Then Logic

Logic and Programming Fundamentals

If-Then logic is like making a decision: when something happens, you take a specific action in response. ๐Ÿค”

๊ฐ„๋‹จ ์†Œ๊ฐœ

If-Then logic is a way of making decisions based on conditions, just like how we make choices in everyday life. ๐Ÿ”„ It's the same as saying 'If it rains, then I'll take an umbrella' or 'If I'm hungry, then I'll eat.' This simple but powerful concept is used everywhere, from basic decision-making to complex computer programming.

Basic Structure ๐Ÿ“

If-Then logic has two main parts: a condition (the 'if' part) and an action (the 'then' part). It's like having a light switch - if you flip it up, then the light turns on.

Decision Making ๐Ÿคน

The condition must be either true or false, like a yes/no question. If the condition is true, the action happens. If it's false, the action doesn't happen. It's like a vending machine: if you put in enough money, then you get your snack.

Multiple Conditions ๐ŸŽฏ

You can combine multiple if-then statements. It's like getting ready for weather: if it's cold, then wear a coat; if it's raining, then take an umbrella; if it's sunny, then wear sunscreen.

Cause and Effect โšก

If-Then logic shows the relationship between causes and effects. It's like dominos - if you push the first one, then all the others will fall in sequence.

  • ๐Ÿšฆ Traffic Light: If the light turns red, then cars must stop; if it turns green, then cars can go.
