Do While D\u00f6ng\u00fcs\u00fc: Bir Detayl\u0131 Anlat\u0131m<\/p>\n

Programlamada d\u00f6ng\u00fcler, belirli bir kod blo\u011funu belirli bir ko\u015ful sa\u011fland\u0131\u011f\u0131 s\u00fcrece tekrar tekrar \u00e7al\u0131\u015ft\u0131rmak i\u00e7in kullan\u0131l\u0131r. Bu, \u00f6zellikle tekrarlayan g\u00f6revleri otomatikle\u015ftirmek veya belirli bir sonu\u00e7 elde edilene kadar i\u015flemleri tekrarlamak istedi\u011fimizde olduk\u00e7a kullan\u0131\u015fl\u0131d\u0131r. Do While d\u00f6ng\u00fcs\u00fc, programlamada en yayg\u0131n kullan\u0131lan d\u00f6ng\u00fclerden biridir ve bu makalede bu d\u00f6ng\u00fc t\u00fcr\u00fcn\u00fc ayr\u0131nt\u0131l\u0131 olarak ele alaca\u011f\u0131z.<\/p>\n

Do While D\u00f6ng\u00fcs\u00fc Nedir?<\/h2>\n

Do While d\u00f6ng\u00fcs\u00fc, ko\u015ful do\u011fru oldu\u011fu s\u00fcrece kod blo\u011funu tekrar tekrar \u00e7al\u0131\u015ft\u0131ran bir d\u00f6ng\u00fc t\u00fcr\u00fcd\u00fcr. Bu d\u00f6ng\u00fc, \u00f6nce kod blo\u011funu \u00e7al\u0131\u015ft\u0131r\u0131r ve ard\u0131ndan ko\u015fulu kontrol eder. Ko\u015ful do\u011fru ise d\u00f6ng\u00fc tekrar ba\u015ftan ba\u015flar. Ko\u015ful yanl\u0131\u015f oldu\u011funda d\u00f6ng\u00fc sonlan\u0131r. Yani, Do While d\u00f6ng\u00fcs\u00fc, kod blo\u011fu en az bir kez \u00e7al\u0131\u015ft\u0131r\u0131laca\u011f\u0131 garanti edilen d\u00f6ng\u00fc t\u00fcr\u00fcd\u00fcr.<\/p>\n

Do While D\u00f6ng\u00fcs\u00fc Nas\u0131l \u00c7al\u0131\u015f\u0131r?<\/h2>\n

Do While d\u00f6ng\u00fcs\u00fc, genellikle \u015fu \u015fekilde ifade edilir:<\/p>\n

“`

D\u00f6ng\u00fcn\u00fcn \u00e7al\u0131\u015fma prensibi \u015fu \u015fekildedir:<\/p>\n

1. **Ba\u015flang\u0131\u00e7:** D\u00f6ng\u00fc ba\u015flar ve kod blo\u011fu ilk kez \u00e7al\u0131\u015ft\u0131r\u0131l\u0131r.
\n2. **Ko\u015ful Kontrol\u00fc:** Kod blo\u011fu \u00e7al\u0131\u015ft\u0131r\u0131ld\u0131ktan sonra ko\u015ful kontrol edilir.
\n3. **Ko\u015ful Do\u011fruysa:** Ko\u015ful do\u011fru ise d\u00f6ng\u00fc tekrar ba\u015fa d\u00f6ner ve kod blo\u011fu tekrar \u00e7al\u0131\u015ft\u0131r\u0131l\u0131r.
\n4. **Ko\u015ful Yanl\u0131\u015fsa:** Ko\u015ful yanl\u0131\u015f ise d\u00f6ng\u00fc sonlan\u0131r ve program\u0131n kontrol\u00fc d\u00f6ng\u00fcn\u00fcn sonuna ge\u00e7er.<\/p>\n

Do While d\u00f6ng\u00fcs\u00fcn\u00fcn nas\u0131l kullan\u0131laca\u011f\u0131n\u0131 g\u00f6steren basit bir \u00f6rnek verelim. A\u015fa\u011f\u0131daki \u00f6rnek, kullan\u0131c\u0131n\u0131n 0 girmesi istenen bir say\u0131 giri\u015fi program\u0131n\u0131 g\u00f6stermektedir:<\/p>\n

“`javascript

Bu \u00f6rnekte, kullan\u0131c\u0131dan bir say\u0131 isteniyor ve say\u0131 0’dan farkl\u0131 oldu\u011fu s\u00fcrece d\u00f6ng\u00fc devam ediyor. Kullan\u0131c\u0131 0 girdi\u011finde d\u00f6ng\u00fc sonlan\u0131yor.<\/p>\n
