struct results
{
  unsigned int id; //id of the team
  unsigned int m; //number of solved problems
};

int comparare(const void * i, const void * j) //compare function for qsort()
{
  return -( *(unsigned int*)i - *(unsigned int*)j );
}

int main()
{

  unsigned int n;
  vector<results> standings; //initializing an array of structs

  scanf("%u", &n); //the size of the vector
  for(unsigned int i=0; i<n; ++i)
  {
    scanf("%u%u", &standings[i].id, &standings[i].m); …
