Displaying Sequential Record
Do you mean: (but it doesn't work, as it only goes back to the beginning of the same record)
Code:
int n;
int pos;
int previous_pos;
fstream f;
f.open("info.txt");
while (1)
{
previous_pos = f.tellg();
getline (f, name);
f >> gender;
f >> age;
f >> staffno;
f >> telpno;
f >> roomno;
cout << "Name: " << name;
cout << "\nGender: " << gender;
cout << "\nAge: " << age;
cout << "\nStaff No.: " << staffno;
cout << "\nPhone No.: " << telpno;
cout << "\nRoom No.: " << roomno << endl <<endl;
cout << "<1> previous \t <2> next \t <0> exit\n";
cin >> n;
pos = f.tellg();
if (n==1)
f.seekg(previous_pos);
if (n==2)
f.seekg(pos);
}
