'while' can be replaced with 'do while'

Reports while loops that could be more effectively written as do-while loops. There are while loops where the code just before the loop is identical to the code in the body of the loop. Replacing with a do-while loop removes the duplicated code. For while loops without such duplicated code, the quick fix is offered in the editor as well, but without highlighting.


foo(); while (x) { foo(); }

Can be replaced with:

do { foo(); } while (x);
