unable to create new file with user entered name

[ak10]

I want to copy the contents of an existing binary file to a new user created one but the file is not getting created.

case 3:  
{  
fio.open("mh.dat",ios::in);
string date;
cout<<"Enter today's date in DD/MM/YYYY(file name for archival record)";
cin>>date;
date+=".dat";
ofstream fo(date.c_str(),ios::out);
while(fio.read((char*)&m,sizeof(m)))
    fo.write((char*)&m,sizeof(m));
fio.close();
fo.close();
break;
}

The file name will not be valid if it contains the / character.
