How to cin to a vector

Question

I\'m trying to ask the user to enter numbers that are put into a vector, then using a function call to count the numbers, why is this not working? I am only able to count t

You probably want to read in more numbers, not only one. For this, you need a loop

int main()
{
  int input = 0;
  while(input != -1){
    vector V;
    cout << "Enter your numbers to be evaluated: " << endl;
    cin >> input;
    V.push_back(input);
    write_vector(V);
  }
  return 0;
}

Note, with this version, it is not possible to add the number -1 as it is the "end signal". Type numbers as long as you like, it will be aborted when you type -1.
