多維數組對象C++ - 如何？

Question

如果有一些麻煩發現如何正確地做到這一點，所以我決定觸摸並繼續解決問題，現在看來它已經有效了。

的代碼是：

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; 

，當我試圖刪除MATR [0] [0]是賽斯分割誤差; yay

我錯過了任何錯誤？

Answer 1

爲什麼不使用矢量？

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

Answer 2

變線Matr[i][j] = new Flight;到Matr[i][j] = new Flight[len]; 和變線Matr[i][j];到delete[] Matr[i][j];
