Nested If &

Nested If

Nested if statements means an if statement inside another if
statement.
When we compare condition while staying in a condition
comparison or we create a if structure within an if structure is called
nested structure. A condition located inside a condition is called
nested condition.

statement within another if…else statement to test one condition
followed by another condition.

Else If Statement

▹ When there are more than two possible actions
to take we sometimes use a serial if statement.

▹ It is called Else If statement

How the Else If statement works?

▹ With a serial If statement each condition is
tested until one is found to be true.

▹ If a condition is found to be true the
conditional statements will be executed and
then control will be passed to the statement
following the End If.

▹ If none of the conditions stated is true the
Else branch is executed and then control will
be passed to the statement following the
End If.
