Annoyance over C++'s requirement to pass a dimension in a 2-d array got me working on a templated Matrix class. I've been coding in C# for a bit, so I'm sure I'm a little rusty here.
Issue is, I get a heap exception as soon as I hit the destructor, which is trying to delete the 2-d array.
Any help gratefully accepted!
template <typename T>
class Matrix {
public:
Matrix(int m, int n) : nRows(m), nCols(n) {
pMatrix = new T * [nRows];
for (int i = 0; i < nCols; i++) {
pMatrix[i] = new T[nCols];
}
}
~Matrix() {
if (pMatrix != NULL) {
for (int i = 0; i < nRows; i++) { delete[] pMatrix[i]; }
delete[] pMatrix;
}
}
T ** GetMatrix() const { return pMatrix; }
T * Row(int i) const { return pMatrix[i]; }
inline T Cell(int row, int col) const { return pMatrix[row][col]; }
inline int GetNRows() const { return nRows; }
inline int GetNCols() const { return nCols; }
private:
int nRows, nCols;
T ** pMatrix;
};
