For Loops: Printing Numbers II in Scala in Scala

Let's see an example where we change the iteration statement.

We can print all even numbers from 2 through 10:

for (i <- 2 to 10 by 2) {
	println(i)
}

The output of this code is:

2
4
6
8
10

Let's break down this code:

• The range starts at 2.

• to 10 means the range includes 10.

• by 2 means we increase our number by 2 every time.

Assignment

Let's print all odd numbers from 7 through 23 using a for loop.

Look at the examples above if you get stuck.
