C++类模板的特化

C++类模板的特化分为两种，一种是全特化，另一种是偏特化。
下面这个例子就是全特化

#include
using namespace std;

template<class T>
class SeqList
{
public:
    SeqList();
    ~SeqList();
private:
    int _size;
    int _capacity;
    T* _data;
};

template<class T>
SeqList::SeqList()
:_size(0), _capacity(0), _data(new T[_capacity])
{
    cout << "SeqList" << endl;
}
template<class T>
SeqList::~SeqList()
{
    delete[] _data;
}
template<>
class SeqList<int>
{
public:
    SeqList(int capacity);
    ~SeqList();
private:
    int _size;
    int _capacity;
