数据结构关于简单顺序表的构建（C++）

//使用结构体构造线性表
typedef struct SeqList
{
    ElemType *elem;
    size_t   capacity;
    size_t   size;
}SeqList;

//使用模板类来构造线性表
const int DefaultSize = 100;

template<typename Type> 
class SeqList
{
public:
    SeqList(int sz = DefaultSize):m_nmaxsize(sz),m_ncurrentsize(-1)
    {
        if(sz > 0)
        {
            m_elements = new Type[m_nmaxsize];
        }
    }
    ~SeqList()
    {
        delete []m_elements;
    }

public:
    int Length() const
    {                    
        return m_ncurrentsize + 1;
    }
    
    int IsEmpty()
    {
        return m_ncurrentsize == -1;
    }

    
private:
    Type *m_elements;
    const int m_nmaxsize;
    int m_ncurrentsize;
};
