多维对象数组c ++ - 如何？

Question

如果有一些麻烦找到如何做到这一点，所以我决定触摸并继续解决问题，现在似乎已经有了它。

代码是：

Flight ***Matr = new Flight**[airportCount];
for(int i = 0; i < airportCount; i++){
    Matr[i] = new Flight*[airportCount];
    for(int j = 0; j < airportCount; j++){
        Matr[i][j] = new Flight;
    }
}
for(int i = 0; i < airportCount; i++){
    for (int j = 1; j < airportCount; j++){
        Matr[i][j];
    }
    delete[] Matr[i];
}
delete[] Matr;

当我尝试删除Matr [0] [0]时，sais分段错误; 耶

我错过了哪些错误？

Answer 1

为什么不使用矢量？

vector < vector < Flight > > Matr( airportCount,
                                   vector < Flight >( airportCount ) )

Answer 2

将行Matr[i][j] = new Flight;更改为Matr[i][j] = new Flight[len]; 并将第Matr[i][j];行更改为delete[] Matr[i][j];
