#includeThis code creates a ByteVector containing the bytes 0x12, 0x34, 0x56, and 0x78. It then calls the toUInt function on this ByteVector and prints the result, which is 305419896. The package library for ByteVector is likely to be Boost. Boost is a C++ library that provides a wide range of functionality, including many utilities for working with bytes and binary data. ByteVector is one of the many libraries included in Boost.#include int main() { ByteVector bv{0x12, 0x34, 0x56, 0x78}; std::cout << bv.toUInt() << std::endl; // output: 305419896 return 0; }
