short age;
public:
void getData(){
cout << "Enter name: "; cin.getline(name,80,'\n');
cout << "Enter age: "; cin >> age;
}
};
/////////////////////////////////////////////////////////////////////////////////////////////////

int main(){

pers.getData();

//open file.
ofstream os("PERSON.DAT", ios::binary);
//write this object to file.
