How can I "reopen" std::cin and std::cout in binary modei c++?

This is implementation dependent. Check with your compiler’s documentation.

For example, suppose you want to do binary I/O using std::cin and std::cout.


Unfortunately there is no standard way to cause std::cin, std::cout, and/or std::cerr to be opened

in binary mode. Closing the streams and attempting to reopen them in binary mode might have

unexpected or undesirable results.


On systems where it makes a difference, the implementation might provide a way to make them

binary streams, but you would have to check the implementation specifics to find out.
