Loops
Looping in Reverse
What if we want the for
loop to log 3
, 2
, 1
, and then 0
? With simple modifications to the expressions, we can make our loop run backward!
To run a backward for
loop, we must:
- Set the iterator variable to the highest desired value in the initialization expression.
- Set the stopping condition for when the iterator variable is less than the desired amount.
- The iterator should decrease in intervals after each iteration.
Instructions
1.
Make a for
loop that loops backwards printing 3
to 0
to the console. Use the >=
comparison operator in your stopping condition and the --
operator in your iteration statement.
