I run this is OK, "d.txt" is created and "12" is appended.
But like this, there will be no effect.Code:#include <fstream.h> int main(){ fstream file; file.open( "d.txt", ios::app ); file.write( "12" ,2 ); file.close(); return 0; }
why? How to do if I must to write in the second form??Code:#include <fstream> using namespace std; int main(){ fstream file; file.open( "d.txt", ios::app ); file.write( "12" ,2 ); file.close(); return 0; }
thx.
