Else Statement

An else statement is used together with if.

It defines what should happen when the if condition is false.

How If–Else Works

Conceptually:

If the condition is true → run the if block
Otherwise → run the else block

Only one of the two blocks will be executed.

Example (Python)

age = 16

if age >= 18:
    print("You are allowed to enter.")
else:
    print("Access denied.")

Explanation:

If age >= 18 is false
The program runs the else block instead

When to Use `else`

Use else when:

you need a fallback action
there are exactly two possible outcomes
one condition is true and the other is false

Summary

else handles the opposite case of if
It runs when the if condition is false
Together, if and else cover two paths
