读取数据的一个C++程序，运行出错，请问问题出在哪？

鄙人写了一个读数据文件的C++程序，程序如下
#include "stdafx.h"
#include<fstream>
#include<iomanip>
#include<string>
#include<cmath>
using namespace std;

    static int NELEM;
    static int NPOIN;
    static int NDIME;
    static int NNODE;
    static int Nx;
    static int Ny;
    static double Dtime;
    static double Ttime;
    static int** Lnods;
    static double** Coord;
    static double* InitialValue;


// Input all basic data of this c++ program

class DataBankbyInput
{
public:

    DataBankbyInput( );
    void InputBasicData(int& NELEM,int& NPOIN,int& NDIME,int& NNODE,
                        int& Nx,int& Ny,double& Dtime,double& Ttime,
                        int** Lnods,double** Coord,double* InitialValue);
    ~DataBankbyInput(){};
};


DataBankbyInput::DataBankbyInput( )
{
}
                    

void DataBankbyInput::InputBasicData(int& NELEM,int& NPOIN,int& NDIME,int& NNODE,
                                     int& Nx,int& Ny,double& Dtime,double& Ttime,
                                     int** Lnods,double** Coord,double* InitialValue)
{
    int ielem,inode,ipoin,idime;

    ifstream input_data_file;
    string filename1;
    cout<<"enter the name of the input file"<<endl;
    cin>>filename1;
    input_data_file.open(filename1.c_str());
    if(input_data_file.fail())
    {
        cout<<"File input_data_file could not be opened"<<endl;
        exit(2);
    }

//
    ofstream output_data_file;
    string filename0;
    cout<<"enter the name of the output file"<<endl;
    cin>>filename0;
    output_data_file.open(filename0.c_str());
    if(output_data_file.fail())
    {
        cout<<"File output_data_file could not be opened"<<endl;
        exit(2);
    }

//   READ THE FIRST DATA CARD, AND ECHO IT IMMEDIATELY.

    input_data_file>>NELEM>>NPOIN>>NDIME>>NNODE>>Nx>>Ny;
    output_data_file<<NELEM<<'  '<<NPOIN<<'  '<<NDIME<<'  '<<NNODE<<'  '<<Nx<<'  '<<Ny<<'  '<<endl;

    cout<<NELEM<<'  '<<NPOIN<<'  '<<NDIME<<'  '<<NNODE<<'  '<<Nx<<'  '<<Ny<<'  '<<endl;

//   READ TIME STEPPING AND SELECTIVE OUTPUT PARAMETERS

    input_data_file>>Dtime>>Ttime;
    output_data_file<<Dtime<<'  '<<Ttime<<endl;

    cout<<Dtime<<'  '<<Ttime<<endl;

    //
    for(ielem=0;ielem<NELEM;ielem++)
    {
        for(inode=0;inode<NNODE;inode++)
        {
            input_data_file>>Lnods[ielem][inode];
            output_data_file<<Lnods[ielem][inode]<<'  '<<endl;
        }
    }

    for(ipoin=0;ipoin<NPOIN;ipoin++)
    {
        for(idime=0;idime<NDIME;idime++)
        {
            input_data_file>>Coord[ipoin][idime];
            output_data_file<<Coord[ipoin][idime]<<'  '<<endl;
        }
    }

    for(ipoin=0;ipoin<NPOIN;ipoin++)
    {
        input_data_file>>InitialValue[ipoin];
        output_data_file<<InitialValue[ipoin]<<'  '<<endl;
    }

    return;
}


int _tmain(int argc, _TCHAR* argv[])
{

    DataBankbyInput data;
    data.InputBasicData(NELEM,NPOIN,NDIME,NNODE,
                        Nx,Ny,Dtime,Ttime,
                        Lnods,Coord,InitialValue);


    return 0;
}
数据文件abc.txt内容如下
2 6 2 4 2 2
0.01  1
1  1  2  5  4
2  2  3  6  5
1  0  0  
2  1  0
3  2  0
4  0  1
5  1  1
6  2  1
1  0
2  0
3  0
4  0
5  0
6  0
我自认为程序读取数据应该没错，可是程序运行不下去，我用cout语句从屏幕输出发现是一串奇怪的数值，请问问题出在哪？请高手赐教。现行谢过！
