NESTED IF … ELSE STATEMENT
If we need to test multiple conditions and execute different sets of statements depending on the
evaluation of the conditions in succession, we use the Nested if … else statement.

first if statement is called the outer if statement, while the if statement

under the outer if statement is called the inner if statement. The
inner if statement is executed only when the outer if test condition Test Condi on 1 No
