顺序表(C++)

最近准备找工作了,在复习数据结构,下面是用C++写的顺序表的一个类(头文件)

#ifndef _SeqList_
#define _SeqList_

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;
	}
	int Length() const{
		return m_ncurrentsize+1;
	}
	int Find(Type x) const;
	int IsElement(Type x) const;
	int Insert(Type x,int i);
	int Remove(Type x);
	int IsEmpty(){
		return m_ncurrentsize==-1;
	}
	int IsFull()
	{
		return m_ncurrentsize==m_nmaxsize-1;
	}
	Type Get(int i){
		return i<0||i>m_ncurrentsize?(cout<<"can't find the element"<<endl,0):m_element[i];
	}
	void Print();
private:
	Type *m_element;
	const int m_nmaxsize;
	int m_ncurrentsize;

};

//部分函数的实现。。。。。

template <typename Type> int SeqList<Type>::Find(Type x) const
{
	for(int i=0;i<m_ncurrentsize;i++)
	{
		if(m_element[i]==x)
			return i;
	}
	cout<<"Can't find the element  you want to find"<<endl;
	return -1;
}

template <typename Type> int SeqList<Type>::IsElement(Type x) const
{
	if(Find(X)==-1)
		return 0;
	return 1;
}

template <typename Type> int SeqList<Type>::Insert(Type x,int i)
{
	if(i<0||i>mm_ncurrentsize+1||m_ncurrentsize==m_nmaxsize-1)
	{
		cout<<"The operation is illegal"<<endl;
		return 0;
	}
	m_ncurrentsize++;
	for(int j=m_ncurrentsize;j>i;j--)
	{
		m_element[j]=m_element[j-1];
	}
	m_element[i]=x;
	return 1;
}

template <typename Type> int SeqList<Type>::Remove(Type x){
    int size=m_ncurrentsize;
    for(int i=0;i<m_ncurrentsize;){
        if(m_elements[i]==x){
            for(int j=i;j<m_ncurrentsize;j++){
                m_element[j]=m_elements[j+1];
            }
            m_ncurrentsize--;
            continue;
        }
        i++;
    }
    if(size==m_ncurrentsize){
        cout<<"can't find the element you want to remove"<<endl;
        return 0;
    }
    return 1;
}
 
template <typename Type> void SeqList<Type>::Print(){
    for(int i=0;i<=m_ncurrentsize;i++)
        cout<<i+1<<":\t"<<m_element[i]<<endl;
    cout<<endl<<endl;
}

#endif

(好像很久没写C++的代码了,比较生疏了,慢慢写,慢慢熟悉)
