这个写法有什么问题？有大佬可以解答下吗？
#include <iostream>
using namespace std;

class X
{
public:
	X(int a=0, int b=0, int c=0)
		:row(a), col(b), value(c)
	{}
	int row;
	int col;
	int value;
	void print()
	{
		cout << row << ' ' << col << ' ' << value << endl;
	}
	void input()
	{
		cin >> row >> col >> value;
	}
};

class Y
{
public:
	Y(int a = 0,int b=0)
		:size(a),start(b)
	{}
	int size;
	int start;
};

void get(X* ar,Y* ca)
{
	ca[1].start = 1;
	for (int i = 1; i <= ar[0].value; i++)
		ca[ar[i].col].size++;
	for (int i = 2; i < ar[0].col + 1; i++)
		ca[i].start = ca[i - 1].size + ca[i - 1].start;
}

void change(X* ar)
{
	X* AR = new X[ar[0].value + 1];
	Y* ca = new Y[ar[0].col + 1];
	get(ar, ca);
	AR[0].col = ar[0].row;
	AR[0].row = ar[0].col;
	AR[0].value = ar[0].value;
	for (int i = 1; i <= ar[0].value; i++)
	{
		AR[ca[ar[i].col].start].col = ar[i].row;
		AR[ca[ar[i].col].start].row = ar[i].col;
		AR[ca[ar[i].col].start].value = ar[i].value;
		ca[ar[i].col].start++;
	}
	for (int i = 0; i <= AR[0].value; i++)
		AR[i].print();
}

int main()
{
	int x, i, j, v = 0;
	cin >> x;
	X** AR = new X * [x];
	for (int u = 0; u < x; u++)
	{
		cin >> i >> j >> v;
		AR[u] = new X[v + 1];
		AR[u][0].row = i;
		AR[u][0].col = j;
		AR[u][0].value = v;
		for (int n = 1; n <= AR[u][0].value; n++)
			AR[u][n].input();
	}
	for (int u = 0; u < x; u++)
	{
		if (AR[u][0].value != 0)
			change(AR[u]);
		else
			cout << AR[u][0].col << ' ' << AR[u][0].row << ' ' << AR[u][0].value << endl;
	}
	return 0;
}

假的吧，在VS中运行正确，怎么放在这上面就不对了？
