c++ - 在类中动态分配二维数组时不断获取“cygwin_exception::open_stackdumpfile”

Question

我一直在尝试编写这个程序，我需要利用动态分配的数组来打印出二维矩阵。我只写cpp文件，不允许修改头文件中的任何内容。

我不断收到异常

0 [main] review2_cis17c_objectarray 4018 cygwin_exception::open_stackdumpfile：将堆栈跟踪转储到 review2_cis17c_objectarray.exe.stackdump

我对学习 c++ 比较陌生；经过深思熟虑，我认为我的 PlusTab.cpp 有问题，我试图将分配的地址分配给类中的构造函数定义的数组。有人可以帮忙，让我知道我在项目中做错了吗？非常感谢！

AbsRow.h：

class AbsRow {
    protected:
        int size;
        int *rowData;
    public:
        virtual int getSize()const = 0;
        virtual int getData(int)const = 0;
};

绝对表.h：

class AbsTabl {
    protected:
        int szRow;
        int szCol;
        RowAray **columns;
    public:
        virtual int getSzRow()const = 0;
        virtual int getSzCol()const = 0;
        virtual int getData(int,int)const = 0; };

PlusTab.h

class PlusTab:public Table {
    public:
        PlusTab(unsigned int r,unsigned int c):Table(r,c){};
        PlusTab operator+(const PlusTab &);
};

RowAray.h

class RowAray:public AbsRow {
    public:
        RowAray(unsigned int);
        virtual ~RowAray();
        int getSize()const{return size;}
        int getData(int i)const{
            if(i>=0&&i<size)return rowData[i];
            else return 0;}
        void setData(int,int);
};

表.h

#include "AbsTabl.h"
class Table:public AbsTabl {
    public:
        Table(unsigned int,unsigned int);
        Table(const Table &);
        virtual ~Table();
        int getSzRow()const {return szRow;}
        int getSzCol()const {return szCol;}
        int getData(int,int)const;
        void setData(int,int,int);
};

PlusTab.cpp：

#include "PlusTab.h"

PlusTab PlusTab::operator+(const PlusTab &t) {
    PlusTab tab(this->getSzRow(), this->getSzCol());
    
    for(int i = 0; i < tab.getSzRow(); i++) {
        for (int j = 0; j <tab.getSzCol(); j++) {
            (tab.columns[i])->setData(j, this->getData(i,j) + t.getData(i,j));
        }
    }
   
    return tab;
}

RowAray.cpp：

#include "RowAray.h"
        
RowAray::RowAray(unsigned int c) {
    size = c;
    
    rowData = new int[c];
}

RowAray::~RowAray() {
    delete []rowData;
}

void RowAray::setData(int i, int value) {
   rowData[i] = value;
}

表.cpp：

#include "Table.h"
#include <cstdlib>
Table::Table(unsigned int r, unsigned int c) {
    
    szRow = r;
    szCol = c;

    columns = new RowAray*[r];

    for (int i = 0; i < r; i++) {
        columns[i] = new RowAray(c);
    }
        
    for (int i = 0; i < r; i++) {
        for (int j = 0; j < c; j++) {
            columns[i]->setData(j, (rand()%90 + 10));
        }
    }
}

Table::~Table() {
    for (int i = 0; i < szRow; i++) {
        delete []columns[i];
    }
    delete []columns;
}

Table::Table(const Table &t) {
    szRow = t.szRow;
    szCol = t.szCol;
    columns = t.columns;
};
 
int Table::getData(int r ,int c) const {
    return columns[r]->getData(c);
};

void Table::setData(int r, int c, int value) {
    columns[r]->setData(c,value);
}

最后是我main.cpp的，我也不允许修改。

 #include <ctime>
#include <iostream>
#include <iomanip>
using namespace std;

//User Libraries
#include "PlusTab.h"

//Global Constants

//Function Prototype
void prntTab(const Table &);

//Execution Begins Here!
int main(int argc, char** argv) {
   //Initialize the random seed
   srand(static_cast<unsigned int>(time(0)));
   
   //Declare Variables
   int rows=3,cols=4;
   
   //Test out the Tables
   PlusTab tab1(rows,cols);
   PlusTab tab2(tab1);
   PlusTab tab3=tab1+tab2;
   
  // Print the tables
   cout<<"Abstracted and Polymorphic Print Table 1 size is [row,col] = ["
           <<rows<<","<<cols<<"]";
   prntTab(tab1);
   cout<<"Copy Constructed Table 2 size is [row,col] = ["
           <<rows<<","<<cols<<"]";
   prntTab(tab2);
   cout<<"Operator Overloaded Table 3 size is [row,col] = ["
           <<rows<<","<<cols<<"]";
   prntTab(tab3);

   //Exit Stage Right
   return 0;
}

void prntTab(const Table &a){
    cout<<endl;
    for(int row=0;row<a.getSzRow();row++){
        for(int col=0;col<a.getSzCol();col++){
            cout<<setw(4)<<a.getData(row,col);
        }
        cout<<endl;
    }
    cout<<endl;
}

我为这么多的代码道歉。这是我第一次发帖，将学习使用该网站！我感谢您的帮助：）
