For loop

The For loop is a bit more complex. It is made of:

• loop variable name
• loop variable initial value
• loop variable end value
• step (increment), by how much the loop variable is incremented in each iteration

TheFor loop replaces the following code:

• declare an Integer i with an initial value
• add While with condition i <= end
• assign i = i + step at the end of While

---

Let's write the same program as before, print the first 5 numbers:

• declare a For loop with variable name i
• set i start value to 1
• set i end value to 5
• set step to 1
• output i in For body

We achieved the same result, but with a lot less code.
Plus, it is more readable than before!
