c++ - fstream and ofstream -


इसमें क्या अंतर है: 

  fstream texfile; textfile.open ( "test.txt");   
 और  
  ऑफस्ट्र्रीम टेक्स्टफ़ाइल; textfile.open ( "test.txt");   
 क्या उनका कार्य समान है?   
 
 
  ऑफस्ट्र्रीम  केवल आउटपुट के लिए तरीके हैं, उदाहरण के लिए यदि आपने  textfile & gt; & gt; जो भी  यह संकलन नहीं करेगा। इनपुट और आउटपुट के लिए  fstream  का उपयोग किया जा सकता है, यद्यपि काम करने वाला यह कन्स्ट्रक्टर /  open ।  
  स्टड :: स्ट्रिंग एस; Std :: ofstream ostream ("फ़ाइल"); Std :: fstream स्ट्रीम ("फ़ाइल", stream.out); ओस्ट्रीम & gt; & gt; रों; // कंपाइलर त्रुटि स्ट्रीम & gt; & gt; रों; // कोई संकलक त्रुटि नहीं है, लेकिन कार्रवाई विफल हो जाएगी।   
 टिप्पणियों में कुछ और महान बिंदु हैं।
