I'm doing a project and I have a vector of objects and I'm not exactly sure how to push items into the members of the object in the vector.

Stat Class:
CODE

class Stat
{
public:
   unsigned int game;        // game number
   int pmRating;             // plus minus rating in the game

   // Overloaded less than operator
   bool operator < (const Stat& s2) const {
      return (pmRating < s2.pmRating);
   }
};


I have the following vector:
vector<Stat> record ;

So I figured to push items in it would be record.pmRating.push_back(itemtopush) but that didn't seem to work tongue.gif

Well you had the right idea, wrong concept.
when you defined vector<Stat> record; you were creating a vector of Stat objects. So if I had Stat MyStat; then I could append it to the vector with record.push_back(MyStat);. i.e you can only add the kind of object you declared the vector for. If you wanted an Vector of pmRatings you would need to use vector<int> either inside the class (if each stat can have more than one pmRating, or outside your code next to record.

Oh somehow I misread that I was given a stat and not a pmRating to add to my vector
