cpp - Template class

Template class is similar to function template , 
We can use the template to instead of type of variable or method of class.
For example : 
 
using namespace std;
 
template <typename T>
class Storage
{
private:
    T m_tValue;
public:
    Storage(T tValue)
    {
         m_tValue = tValue;
    }
 
    ~Storage()
    {
    }
 
    void Print()
    {
        std::cout << m_tValue << std::endl;;
    }
};

int main()
{
    // Define some storage units
    Storage<int> nValue(5);
    Storage<double> dValue(6.7);
 
    // Print out some values
    nValue.Print();
    dValue.Print();
}
