C++-6

使用模板类，实现顺序栈。

#include <iostream>

using namespace std;
template <typename T>
class Seqlite
{
    T data[30];
    int len=0;
public:
    void head_inst(T date);
    void head_dele();
    void show();
};
template <typename T>                     //头插
void Seqlite<T>::head_inst(T date)
{
    if(len>=30)
    {
         cout << "be already full" << endl;
         return;
    }
    for(int i=len;i>0;i--)
        data[i]=data[i-1];
    data[0]=date;
    len++;
}
template <typename T>                     //头删
void Seqlite<T>::head_dele(){
    if(len==0)
    {
        cout << "empty" << endl;
        return;
    }

    for(int i=0;i<len-1;i++)
        data[i]=data[i+1];
    cout << data[0] << " is out " << endl;
    len--;
}
template <typename T>
void Seqlite<T>::show()
{
    if(len==0)
    {
        cout << "empty" << endl;
        return;
    }
    for(int i=0;i<len;i++)
        cout << data[i] << "\t" ;
    cout << endl;
}
int main()
{

    Seqlite<int> s1;
    s1.head_inst(1);
    s1.head_inst(2);
    s1.head_inst(3);
    s1.show();
    s1.head_dele();
    s1.show();
    return 0;
}
