file to vector, edit vector, vector to file

[jmcco018]

I am very confused on how to do this.
I have a file that tells you if a plane seat is available or not.
I want it so that upon the user booking a seat, the singular line that corresponds to that seat in my file is editted, leaving the rest the same.

What I have so far is:


vector<char> plane;
ifstream myfile("plane1.txt");
while(!myfile.eof())
{getline(myfile, line); plane.push_back(line); count++;}
plane.erase(plane.begin()+s);
plane.insert(plane.begin()+s, tempt);
ofstream out("plane1.txt", ios::out || ios::binary);
std::vector<plane>::iterator pos(plane.begin());
for(pos; pos !=plane.end(); pos++)
{
out.write ???????
}

where s is decided by the row/column combination and tempt is entered by the user.

Am I going in the right direction? Also, what libraries do I need to include in my .cpp?
