Condition:
Following comparison operators can be used:
! = does not equal
== equals
< smaller
<= less than or equal to
> larger
> = greater than or equal to
Initialization follows free rules because the
expression is specified in the (()) block.
Variable I has the role of counter.
Change:
You can use any expression that can be
interpreted in the (( )) block, e.g.:
++ increases value of variable by one
- decreases value of variable by one
and more ...
Can only be applied to integers in (( )).
It is recommended to change the counter only in the reserved place within for loop
notation.
