Using a Sequence of if Statements with else Clauses

You can chain if statements with else clauses together to create a sequence of expressions that get tested in order. The statement associated with the first expression to test true is executed; otherwise, the statement associated with the final (and optional) else clause is run. Here’s the form such a series would take:

if (expression1)
    statement1;
else if (expression2)
    statement2;

...

else if (expressionN)
    statementN;
else
    statementN+1;
