For Loop
For Loop is a bit more complex command.
You give it a variable name, its initial value, its end value, and a step (increment).
It is the same as if you:
- Declared an Integer
i
with an initial value - Added While with condition
i <= end
- Assigned
i = i + step
at the end of While
Let's write the same program as before, print 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!
