c++ - Whats the difference between ofstream "<<" and Write -


i had opened file in binary mode , write file .

   ofstream ofile("file.txt",ios_base::binary)     int = 1;     float f = 0.1;     string str = 10;     ofile<<a<<f<<str;

like know difference between writing using "<<" , using "ofile.write" . best , effective write in binary mode.

operator<< format data text. whereas write output data in same format it's stored in ram. so, if writing binary files, want use write.

however, if writing non-pod types, need careful. can't say:

write( &mystring, sizeof(std::string) );

you need have way output actual data, not stored in class or struct itself.
