c++ creates 2d dynamic arrays with memory release issues

As follows:

#include <iostream>
#include <windows.h>
using namespace std;
int main()
{
  cout << "create dynamic two-dimension array..." << endl;
  int sizeX = 5;
  int sizeY = 8;
  //  To apply for 
  double** array = new double*[sizeX];
  for (int i = 0; i < sizeX; i++) {
    array[i] = new double[sizeY];
  }
  for (int i = 0; i < sizeX; i++) {
    for (int j = 0; j < sizeY; j++) {
      array[i][j] = i + j;
    }
  }
   for (int i = 0; i < sizeX; i++) {
    for (int j = 0; j < sizeY; j++) {
      cout << array[i][j];
    }
    cout << endl;
  }
  //  The release of 
  for (int i = 0; i < sizeX; i++) {
      delete[] array[i];
  }
  delete[] array;
  system("pause");
  return 0;
}

As above, the results are as follows:

create dynamic two-dimension array...
01234567
12345678
23456789
345678910
