WA in 11323. 2D-SORT

[annnDi123_]

Hello guys, i have a problem and I cant see the solution. I have this program in c++ and i'm trying to solve the following problem:
spoj.com/problems/SORT2D/

My program works fine for the output and I cant find the mistake because it's throwing Wrong Answer, but for the following input its working okey.
Please, i would appreciate any help.
Thank you very much. I'm dying over here
This is my code:

#include <iostream>
#include <vector>
#include <algorithm>
#include <utility>
#include <iterator>
using namespace std;
vector <pair <double, double> > arrayWhole;
class sort_pred
{
	public:
    bool operator()(const pair <double, double> &right, const pair <double, double> &left) const {
		if ((left.first > right.first) || (left.first == right.first && left.second < right.second))
		{
			return left > right;
		}
    }
};
void sortPoints()
{
	sort(arrayWhole.begin(), arrayWhole.end(), sort_pred()); 
}
int main()
{
	int numberTests = 0;
	scanf("%d",&numberTests);
	double size = 0;
	scanf("%Lf", &size);
	int start = 0;
	while (start < numberTests)
	{
		double tmpNumber1, tmpNumber2;
		for (int i = 0; i < size; i++)
		{			
			scanf("%Lf %Lf", &tmpNumber1, &tmpNumber2);
			arrayWhole.push_back(make_pair(tmpNumber1, tmpNumber2));
		}
		sortPoints();
		for (int x = 0; x < arrayWhole.size(); ++x )
		{
			cout << arrayWhole[x].first << " " << arrayWhole[x].second<<endl;
			cout <<endl;
		}
		arrayWhole.clear();
		start++;
	}
	system("PAUSE");
	return 0;
}

First of all I stongly recommend to get rid of all floating data types. There's no need to use double.

Running your code on ideone results in an empty output (C++ 11) or compilation error (C++ 4.8.1).

system("PAUSE") has to be remove for submission.

Hey, yes, i always remove the System("PAUSE"), so this is not the problem when uploading.
I already changed the types to int but cant get the program to work, so I still dont know where the problem is.
Thank you for help.

[daft_wullie]

You could post your updated code. Did you check your code on ideone?

When i change my vector pairs to int i get a problem in running it in visual studio.
This is my latestu code, i tested it in ideone and yes, the output is empty, i dont know why.
I have no more ideas on what to do.

#include <iostream>
#include <vector>
#include <algorithm>
#include <utility>
#include <iterator>
using namespace std;
vector <pair <double, double> > arrayWhole;
class sort_pred
{
	public:
    bool operator()(const pair <double, double> &right, const pair <double, double> &left) const {
		if ((left.first > right.first) || (left.first == right.first && left.second < right.second))
		{
			return left > right;
		}
    }
};
void sortPoints()
{
	sort(arrayWhole.begin(), arrayWhole.end(), sort_pred()); 
}
int main()
{
	int numberTests = 0;
	scanf("%d",&numberTests);
	double size = 0;
	scanf("%Lf", &size);
	int start = 0;
	while (start < numberTests)
	{
		double tmpNumber1, tmpNumber2;
		for (int i = 0; i < size; i++)
		{			
			scanf("%Lf %Lf", &tmpNumber1, &tmpNumber2);
			arrayWhole.push_back(make_pair(tmpNumber1, tmpNumber2));
		}
		sortPoints();
		for (int x = 0; x < arrayWhole.size(); ++x )
		{
			cout << arrayWhole[x].first << " " << arrayWhole[x].second<<endl;
			cout <<endl;
		}
		arrayWhole.clear();
		start++;
	}
	return 0;
}
