class Salary
{
public:
string id;
int salary;
Salary(string ID, int S)
{
id = ID;
salary = S;
}
Salary(){};
void Save();
void Load();
};

void Salary ::Save()
{

Salary em ("6001", 4000);
Salary em2("43098", 2938);
ofstream os("data.txt", ios_base::out|ios_base::binary );
os.write(reinterpret_cast<char*>(&em), sizeof(em));
os.write(reinterpret_cast<char*>(&em2), sizeof(em2));
os.close();

}
void Salary::Load()
{
ifstream is("data.txt", ios_base::in|ios_base::binary);
if(is)
{
while(is)
{
Salary emp ;
is.read(reinterpret_cast<char*>(&emp), sizeof(emp));
cout << emp.id << " " << emp.salary << endl;
}
}
else
{
cout << "can not open" << endl;
}

}
int main()
{

Salary A;
A.Save();
A.Load();
return 0;
