Help regarding Loops?

[bitong]

I'm a little bit confuse with regard to our subject in C..We are now with the Loops..and I was just wondering if given a problem, can you use Do-while loops instead of a for loops or vise versa? are there instances that you must use a Do-while loops instead of a for loops or a while loop? or you can use any types of loops in any given problem?

With the use of the break statement any loop can be used to mimic any other loop.

Generally I would use for loops unless I had a specific reason to use a while or do-while loop.

The do-while loop is unique of the 3 in that the loop code clock is always executed at least once. You will sometimes get situations where this is useful.

I would only use the while loop if I didn't really have a control variable that required updating on every iteration.

I tend to think of using a for loop when I know how many interations I want it to do, as when iterating over an array of a known size, and using a while loop when the number of iterations is unknown in advance, perhaps dependent on the users' choice of whether to proceed.
