Guys, what kind of loop is better to use when entering data?

Question

C++ / C#

I am learning and still can not decide which one is better to use, it will be useful to learn from you

Answer 1

Any finite loop on machine instructions looks like a condition check + conditional jump.
In general, the same goto wrapped in a beautiful wrapper.
So for the processor there is no difference. It is for the person who will read/maintain the program, so write the code as if it would be accompanied by a bloodthirsty psychopathic maniac who knows where you live.
Make your code clear and readable.

Answer 2

No cycles needed, goto better .

Answer 3

var ret = true;
                    do
                    {
                        var key = Console.ReadKey().KeyChar;
                        if (key == 'a')
                        {
                            _replaceMode = ReplaceMode.Override;
                            ret = false;
                        }
                        if (key == 'b')
                        {
                            throw new ArgumentException($"File exist, breaking:  {newWikiPageUrl}");
                        }
                        if (key == 'r')
                        {
                            ret = false;
                        }
                    } while (ret);
