Simple matrix example using C++ template class
- by skyeagle
I am trying to write a trivial Matrix class, using C++ templates in an attempt to brush up my C++, and also to explain something to a fellow coder.
This is what I have som far:
template class<T>
class Matrix
{
public:
Matrix(const unsigned int rows, const unsigned int cols);
Matrix(const Matrix& m);
Matrix& operator=(const Matrix& m);
~Matrix();
unsigned int getNumRows() const;
unsigned int getNumCols() const;
template <class T> T getCellValue(unsigned int row, unsigned col) const;
template <class T> void setCellValue(unsigned int row, unsigned col, T value) const;
private:
// Note: intentionally NOT using smart pointers here ...
T * m_values;
};
template<class T> inline T Matrix::getCellValue(unsigned int row, unsigned col) const
{
}
template<class T> inline void Matrix::setCellValue(unsigned int row, unsigned col, T value)
{
}
I'm stuck on the ctor, since I need to allocate a new[] T, it seems like it needs to be a template method - however, I'm not sure I have come accross a templated ctor before.
How can I implemnt the ctor?
