我来补答

#include
using namespace std;
class CMatrix
{
public:
CMatrix(unsigned long m,unsigned long n);
CMatrix(CMatrix& A); // COPY构造函数,必须要.
CMatrix(){_m=0;_n=0;_data=NULL;}//无参数构造函数,必须要.
CMatrix(){if(_data!=NULL)delete _data;}
void DisplayOnCMD();
bool SetCell(unsigned long x,unsigned long y,double data);
double GetCell(unsigned long x,unsigned long y);
unsigned long GetM(){return _m;}
unsigned long GetN(){return _n;}
CMatrix operator+(const CMatrix &A);
CMatrix operator=(const CMatrix &A);
private:
unsigned long _m,_n;
double* _data;
};
CMatrix::CMatrix(unsigned long m,unsigned long n)
{
_m=m;_n=n;
_data=new double[_m*_n];
for(int i=0;i
