c++ 구조체와set 을 써서 sorting 하기 예제

 
struct Data {
 
    int id, score;
 
    void insert(int _id, int _score) {
        id = _id, score = _score;
    }
 
}Student[MAX_ID];
 
 
struct Comp
{
 
    bool operator () (int a, int b) const {
 
        if (Student[a].score != Student[b].score)
            return Student[a].score < Student[b].score;
 
        return Student[a].id < Student[b].id;
    }    
};
 
set <int, Comp> StudentSet[4][3];
