Initialize i then execute the code block before comparing i to 3?
In the for loop, the instructor says that i is initialized to 0, then the code block is executed, then i is compared to 3. If it is less than 3, it's auto-incrememented.
Isn't it: initialize, compare, execute, increment, compare again?
Yes, you should be correct. The instructor's wording would imply that a for loop would always be executed at least once which I don't believe is true.
A do/while loop on the other hand does execute at least once because the condition is evaluated at the end.
