4. How do you code choices and decisions?
IF then ELSE Logic

5. If then else Logic – Weather Example
IF it rains then
bring an umbrella
IF it snows then
wear boots
ELSE wear sunglasses

6. ELSE is Optional IF it rains then IF it snows then IF it is sunny then
You can use a series of IF statements without an ELSE
Example:
IF it rains then
bring an umbrella
IF it snows then
wear boots
IF it is sunny then
wear sunglasses
