io - c++ eof and failbit in the middle of reading binary file -


i have troubles reading binary file. seems not read end:

// file size ifs.open (infile.c_str(), ios::binary | ios::ate); cout << "file size:  " << ifs.tellg() << endl;; ifs.close();  // read file ifs.open (infile.c_str(), ios::in | ios::binary); int counter = 0; char c = 0; (counter = 0; ifs; ++counter)     ifs >> c;  cout << "last char:  " << int(c) << endl; cout << "read bytes: " << counter << endl; cout << "fail? " << (ifs.fail() ? "yes" : "no") << endl; cout << "bad?  " << (ifs.bad() ? "yes" : "no") << endl; cout << "eof?  " << (ifs.eof() ? "yes" : "no") << endl; ifs.close();

below output. don't understand why eofbit in middle of file , why comes failbit:

file size:  289384 last char:  1 read bytes: 288598 fail? yes bad?  no eof?  yes

i on unix system

i did test , discovered problem. it's obvious once add ofs << c loop.

it not reading white-space.

you can fix either adding #include <iomanip> , ifs >> noskipws, or using binary input functions ifs.get(c)
