duplicates - How to avoid while-loop code duplication? - 


  स्ट्रिंग s = कंसोल.रिडलाइन (); जबकि (एस! = नल) {// कुछ करना / / .... s = कंसोल.रिडलाइन (); }   
 उपरोक्त कोड इनपुट प्राप्त करना, इसे सत्यापित करने, उसे संसाधित करना और फिर इनपुट करना है, लेकिन जाहिर है,  s = Console.ReadLine ();  कोड दोहराव।  
 दोहराव से बचने के लिए क्या युक्तियां हैं?   
 
 
 पायथन में (जहां कम से कम एक पुनरावृत्ति की गारंटी देने के लिए कोई  do-while  लूप नहीं है), यह चाल एक स्पष्ट विराम के साथ अनंत लूप का उपयोग करना है।  
  जबकि (सत्य ) // या जो कुछ भी सच बिना शर्त का मूल्यांकन करता है {s = Console.ReadLine (); यदि (एस == रिक्त) {ब्रेक; } // कुछ करो}
