Document operation of the C + + If the documents do not exist, the new document, as follows : The problem is there is no documentation, they can create documents, but the document is empty, can write? Why? Brother asked, I want to write a number of documents 0, how convenient Thank you! #include "Iostream>; #include "Fstream>; Using namespace std; Int main () { Fstream fs; Fs.open ( "ttt," in|ios ios : : : : : : binary|ios out); 4003rd fs.close (); If (!fs.is_open ()) { Fs.open ( "ttt," out|ios ios : : : : binary); Int i Z Int j Z While (i++<10) 4003rd fs.put (j); Fs.write ((const char*) &j, sizeof (int)); Return 1; } Return 0 } Document operation of the C + + 1. Open mode option is to establish the parameters for the document can be written specifically to check msn. 2. 0 can be put directly to write a format string or reuse write. Document operation of the C + + Note : If you write the 0 to add more exact, which can be used UNION, into faster. Document operation of the C + + --> This is not the two reasons? [code] #include "Iostream>; #include "Fstream>; Using namespace std; Int main () { Fstream fs; Fs.open ( "ttt," in|ios ios : : : : : : out|ios binary); Int i Z Int j Z While (i++<10)         { Fs.put (0); Fs.write ((const char*) &j, sizeof (int));         } Fs.close (); Return 0 } [/code] This can write [/quote]-->--> [ Closed window ]
