利用模板类完成顺序表

#include <iostream>using namespace std;//模板类
template <typename T>
class SeqTab{T arr[20];int maxsize;
public:SeqTab():maxsize(0){}void Insert(T a);void Search(T a);void Delete(int index);void Show();
};//尾插
template <typename T>
void SeqTab<T>::Insert(T a){if(maxsize == 20){cout << "FULL" << endl;return;}arr[maxsize] = a;maxsize++;
}//显示所有值
template <typename T>
void SeqTab<T>::Show(){for (int i=0; i<maxsize; i++) {cout << arr[i] << ' ';}cout << endl;
}//删除指定数组下标的值
template <typename T>
void SeqTab<T>::Delete(int index){if(maxsize == 0){cout << "NULL" << endl;return;}for (int i=index; i<maxsize-1; i++) {arr[i] = arr[i+1];}maxsize--;
}//查找值
template <typename T>
void SeqTab<T>::Search(T a){if(maxsize == 0){cout << "NULL" << endl;return;}for (int i=0; i<maxsize; i++) {if(arr[i] == a){cout << "arr[" << i << "]=" << a <<endl;return;}}cout << "NOT FOUND" << endl;
}int main()
{SeqTab<int> seq;for (int i=0; i<20; i++) {seq.Insert(i);}seq.Show();seq.Insert(20);seq.Delete(0);seq.Show();seq.Insert(20);seq.Show();seq.Search(5);return 0;
}
