Transforming one loop in another one

Question

is it theoretically possible to transform any loop into any other loop?
For example: a while loop in a do-while loop or a for-loop in a while loop?
Tnx

I don't need to write an algorithm to convert one loop in any given other loop. I just need to know if it is possible to change one loop in another by modifying the code.One easy, scientific way to answer an "Is it possible to ..."-style questions is to provide an algorithm that does what is asked for and works in ever case. If such an algorithm exists, then the answer to the question is "Yes, it's possible".
I was trying to direct you to a rather simple (but possibly not ideal) algorithm to do that conversion.
for example:
int example = 5;
do
example++;
while ( example<5 )
First step: convert the loop to an endless loop:
int example = 5;
do {
  example++;
} while (true);Second step: add logic "manually"
int example = 5;
do {
  example++;
  if (!(example < 5)) {
    break;
} while (true);Third step: convert endless do-while loop into any other endless loop you want (left as an exercise for the reader).
Of course this is an easy example but i need to know if it is theoreticaly possible to to this for any given loop into any other given loop.Well, step 1 and step 3 are trivially possible in every case. The only thing you need to make sure is that step 2 is possible in every case. And I personally am pretty sure that it's possible in every case.
