Thread: write() function

I managed to write type of string as following

Code:

ofstream& operator<<(ofstream& stream, const Data& d) {
    int len;
    char *str;
    str = new char[80];
    string name = "me";

    len = static_cast<int>(d.name.length());
    strncpy(str, name.c_str(), len);
    stream.write(reinterpret_cast<const char *>(&len), sizeof(int));
    stream.write(reinterpret_cast<const char *>(str), len);
    return stream;

    len = static_cast<int>(sizeof(d.num));
    stream.write(reinterpret_cast<const char *>(&len), sizeof(d.num));
    stream.write(reinterpret_cast<const char *>(d.num), len);
}

The overloaded operator above is supposed to work for:
outFile << Data;
But I cant get the d.num to print.

any clue??
