For Loops: Printing Numbers in Scala in Scala

We can achieve many different outcomes with for loops.

It's all about tuning the initialization, condition and iteration statements.

For example, we can print all numbers from 2 through 6:

for (i <- 2 to 6) {
	println(i)
}

The output of this code is:

2
3
4
5
6

Let's break down this code:

• The range starts at 2.

• to 6 means the range includes 6.

• The range increases by 1 by default.

Assignment

Let's print all numbers from 3 through 10 using a for loop.
