4. if / else

• What to do when the if condition is false?.

• The else clause means otherwise.

• It is usually used to indicate complementary conditions.

• The if / else conditions can be seen as a car arriving at a fork in the road.

• Depending on the result of a condition, the car can take the upper or lower road.

• The two codes below do the same thing but one uses if / else conditions.
