HOW DO YOU WRITE IN A .BIN FILE AN ARRAY WITH THE FOLLOWING SPECS:

double A[12[17];

THEN HOW DO YOU READ THE FILE SO YOU ARE ABLE TO GET BACK THE DATA?

What's a problem?

CODE

    double a[12][17];
    int     b[40];
    ... // populate a, b...
    const char* fname = "xxxx.xxx";
    std::ofstream fout(fname,std::ios::binary);
    fout.write((const char*)a,sizeof a);
    fout.write((const char*)b,sizeof b);
    fout.close();
then

CODE

    ...
    std::ifstream fin(fname,std::ios::binary);   
    fin.read((char*)a,sizeof a);
    fin.read((char*)b,sizeof b);
    fin.close();
or (non-stop)

CODE

    std::fstream f(fname,std::ios::binary);
    f.write((const char*)a,sizeof a);
    f.write((const char*)b,sizeof b);
    ...
    f.seekg(0); // rewind op
    f.read((char*)a,sizeof a);
    f.read((char*)b,sizeof b);
    ...
    f.close();
Add error checking and go on!..
