Example of a while loop that can't be written as a for loop

Question

I know a while loop can do anything a for loop can, but can a for loop do anything a while loop can?

Please provide an example.

Answer 1

In C-like languages, you can declare for loops such as this:

for(; true;)
{
    if(someCondition)
       break;
}

In languages where for is more strict, infinite loops would be a case requiring a while loop.
