✨Vòng lặp do while

Fortran

With legacy FORTRAN 77 there is no DO-WHILE construct but the same effect can be achieved with GOTO:

With Fortran 90 and later, the do-while loop is actually the same as the for loop.

PL/I

The PL/I DO statement subsumes the functions of the post-test loop (do until), the pre-test loop (do while), and the for loop. All functions can be included in a single statement. The example shows only the "do until" syntax.

declare counter   fixed initial(5);
declare factorial fixed initial(1);
do until(counter<=0);
  factorial = factorial * counter;
  counter = counter - 1;
  end;
put(factorial);

Python

Python lacks a specific do while flow control construct. However, the equivalent may be constructed out of a while loop with a break.

Racket

Racket, cũng như các hiện thực khác của Scheme, dùng "named-let" như một cách thông dụng để hiện thực vòng lặp:

Compare this with the first example of the while loop example for Racket. Be aware that a named let can also take arguments.

Racket and Scheme also provide a proper do loop.
