c++创建二维动态数组与内存释放

#include <iostream>
#include <windows.h>
using namespace std;
int main()
{
    cout << "create dynamic two-dimension array..." << endl;
    int sizeX = 5;
    int sizeY = 8;
    // 申请
    double** array = new double*[sizeX];
    for (int i = 0; i < sizeX; i++) {
        array[i] = new double[sizeY];
    }

    for (int i = 0; i < sizeX; i++) {

            array[i][j] = i + j;
        }
    }

     for (int i = 0; i < sizeX; i++) {

        }
        cout << endl;
    }

    // 释放

    }
    delete[] array;
    system("pause");
