Hello,
I need to write a bunch of unsigned integers to std::ofstream
in binary mode:
std::ofstream f;
f.open("some path", std::ios::out | std::ios::binary);
// some loop
{
unsigned int k = get_k(); // may product numbers from 0 to 65535
f << k;
}
f.close();
They are written to the output file "as is" w/o any delimiter. So when I'm trying to read them back (expecting to get what I wrote) using std::ifstream
I get very strange values. What I'm doing wrong?
Or I should to put ' '
(space) to the stream after any added number to separate them?
Thanks.
