Once a stream goes into an error state, 100 if myFile An error occurred myFile gcount returns the number of bytes read., all future read operations will fail An example includefstream h char buffer 100 ifstream myFile data bin ios in ios binary adbuffer If you want to do this the C way, do it like this includefstream include iterator includealgorithm> int main std ifstream input C Final gif std ios binary; std ofstream output C myfile gif std ios binary; std copy( std istreambuf iterator char input std istreambuf iterator char.

The usual stream classes ofstreamoutput file stream) , ifstreaminput file stream) are still the types of streams to use A an additional type called an fstream is provided which allows for files that can be written to , this is often the case., read from if this is a desirable propertyin the design of database type programs
I have got a file that contains data for multiple jpegsalong with some garbage i need to extract binary from this file, create jpegs I., filter out the garbage
I Want to read a set of data contains in a file which are in different types int, string types) string type data contain more than one word., double A few things I would do differently: static char ReadAllBytes const char filename, int read) ifstream ifs filename, ios binary ios ate ifstream pos type pos ifs tellg What happens if the OS supports really big files It may be larger than 32 bits This will silently truncate the value/ int length pos;.
