How do I know which loops to use?

Question

Whenever I get a programming exercise, I have difficulty with selecting which loop to use. Do you having any tips or guidelines I could use to select the right loop to use?

Answer 1

When you know the number of iterations then use FOR LOOP. When you don't know the number of iterations then use WHILE LOOP. Use DO WHILE LOOP if you feel that something has to be executed atleast once.

For conditional statements you can replace your 'IF ELSE' ladder with SWITCH.
