Else If Statement

An else if statement allows a program to check multiple conditions in sequence.

It is used when there are more than two possible cases.

How Else If Works

Conceptually:

Check the first condition
If false, check the next condition
Continue until a condition is true
If none are true, run the else block (optional)

Only one block will be executed.

Example (Python)

score = 75

if score >= 90:
    print("Grade: A")
elif score >= 75:
    print("Grade: B")
elif score >= 60:
    print("Grade: C")
else:
    print("Grade: F")

Explanation:

Conditions are checked from top to bottom
The first matching condition is executed
The rest are skipped

When to Use `else if`

Use else if when:

you have multiple conditions
conditions are mutually exclusive
only one outcome should happen

Summary

else if handles multiple conditions
Conditions are checked in order
Only one block runs
