Reading Binary Data from std::cin with Ease

When dealing with binary data, which lacks formatting, std::cin might not be the best choice if you're looking to convert it into a string or a stringstream directly.

Reopening std::cin in Binary Mode

std::cin is not typically opened with the ios_binary flag set. To enable binary reading, it's necessary to reopen it accordingly. However, this is not a standard feature.

Using cin.read()

Once std::cin is opened in binary mode, you can utilize the cin.read() function to retrieve bytes. If you're confident that there's no distinction between text and binary in your system (and portability is not a concern), you can directly use cin.read() for binary data.
