Under the control of the boolean test, one or theother will be taken, but not both. For example, the famous Robert Frost poem is a thinlydisguised comment on the importance of the if/else structure...

What is a nested IF statement?
Nested if Statements • The statement executed as a result of an if statement or else clause could be another if statement • These are called nested if statements • Indentation does not determine which if and else matches with.
