 The format for `while` loops is:
 
 while condition {


/*:
### `for`
You can also define for loops in the following format
*/

for var index = 0; index < 3; index++ {
    println("I can count to \(index)")
}
/*:

The format is like the following

for initialization; condition; increment {
statements

    println("I live in \(city)")
}

/*:
The `for-in` loop is similar to a Python `for` loop or a Java `enhanced for` loop.

We can also use a `for-in` with a range of numbers:
*/

for index in 1...3 {
    println("I can count to \(index)")
