Using a switch()… complex statement

With the if()… else… statement, the conditional expression evaluates to only one of two values – true or false. But what if we had a single result that could have multiple values, with each value requiring a different bit of code execution?

For this, we have the switch()… statement. This statement evaluates an expression to a single result and selects a pathway where the result matches the known values that we care about.

The syntax of the switch()… statement is as follows:

switch( expression )  {

  case constant-1 :    statement-1

  case constant-2 :    statement-2

  …

  case constant-n :    statement-n

  default :            statement-default

}

Here, the expression evaluates a single result...
