What is std::print binary output (C++23)?

Question

Accepted Answer

**std::print** supports binary output mode. ```cpp #include // Binary output to stdout std::print(std::cout, "\x00\x01\x02"); // Binary to file std::FILE* f = fopen("data.bin", "wb"); std::print(f, "\x00\x01\x02"); fclose(f); // Format with binary output uint32_t value = 42; std::print(std::cout, "{}", std::span(reinterpret_cast(&value), 4)); // Binary + text std::print(std::cout, "Header: "); std::print(std::cout, "\xDE\xAD"); std::print(std::cout, " "); // Raw bytes std::string data = "\x00\x01\x02\x03"; std::print(std::cout, "{}", data); // Raw bytes, no escaping // Hex dump std::print(std::cout, "{:02x}", 255); // "ff" ``` **Use cases:** - Writing binary files. - Network protocols. - Serialization.
