An example of how to serialize / deserialize a C++ struct to and from a disk file.

objSerialization.cpp

struct OBJECT{ // The object to be serialized / deserialized
public:
  // Members are serialized / deserialized in the order they are declared. Can use bitpacking as well.
	DATATYPE member1;
	DATATYPE member2;
	DATATYPE member3;
	DATATYPE member4;
};

void write(const std::string& file_name, OBJECT& data) // Writes the given OBJECT data to the given file name.
{
	std::ofstream out;
	out.open(file_name,std::ios::binary);
	out.write(reinterpret_cast<char*>(&data), sizeof(OBJECT));
	out.close();
};

void read(const std::string& file_name, OBJECT& data) // Reads the given file and assigns the data to the given OBJECT.
{
	std::ifstream in;
	in.open(file_name,std::ios::binary);
	in.read(reinterpret_cast<char*>(&data), sizeof(OBJECT));
	in.close();
};

From what I know, this example showcase no way of serializing or de-serializing and object. More of how to read and write binary files.

Or perhaps read/write function already serialize and de-serialize the object?
