while loop requires explicit condition, for loop doesn't, why?

Question

In C++ you are allowed to have an empty condition inside the for-loop, for example as in for (;;) or for (int x = 0;; ++x). But you can\'t do

Answer 1

The difference between logical statements used in while() and for(;;) loops is that:

• in case of for the statement defines condition of exiting the loop

• in case of while() the statement defines condition of executing the loop

Assuming that, you see that to enter a loop, you need at least a condition of executing, not a condition of exiting.
