//
// The last two exercises were functionally identical. Continue
// expressions really show their utility when used with 'continue'
// statements!
//
// Example:
//
//     while (condition) : (continue expression) {
//
//         if (other condition) continue;
//
//     }
//
// The "continue expression" executes every time the loop restarts
// whether the "continue" statement happens or not.
//
