Writing/Reading from a file!

crb8v2 (7)
A friend and I are trying to keep our minds fresh over break by creating a program that rates girls, excuse image that throws...

I am at a road block finding a way to store the information of each girl, such as a string for their name and ints for their scores. I cannot find a way to reference each of them so I can make a comparative statement! My first reaction was to write the data to a file. The program below only stores one number.

Arrays were another idea I looked into. If I understand correctly, data cannot be stored in an array like that.

Thanks in advance!

Well you could try to use an array but you would need to for-loop through the array before/while you put that data into your file.

However, I would be hard-pressed to think that there is any more efficient way of storing a series of data-points and with no iteration to place that data into a file.

I hope I've help,

Why don't you use a struct for the girl data and store them in a vector? You could easily do all sort of operations like sorting, filtering and searching.

struct Girl
{
  Girl(int cute, int smart, int crazy)
  {
    this->crazy = crazy;
    this->smart = smart;
    this->cute = cute;
  }

  double getRating()
  {
    return double(cute + crazy + smart) / 3.0;
  }

  int cute;
  int smart;
  int crazy;
};

Thanks for the suggestions, from both of you. Thomas1965, I do not believe we went over structures in class yet (maybe we did). I will review my textbook and research into both suggestions. I may private message you moving forward. :)
