C++ 类模板

Array模板类

#include<iostream>using namespace std;template <class T>class Array{int size;T* aptr; //T为类型参数public:Array(int slots=1){size=slots;aptr=new T[slots];//为动态数组分配内存空间}void fill_Array();void disp_Array();~Array(){delete[] aptr;}};template <class T>void Array<T>::fill_Array(){cout<<"输入"<<size<<"个数据"<<endl;for(int i=0;i<size;i++){cout<<"第"<<i+1<<"个数据:";cin>>aptr[i];}}template <class T>void Array<T>::disp_Array(){for(int i=0;i<size;i++)cout<<aptr[i]<<" ";cout<<endl;}int main(){Array<char> ac(5);//Array<char>为模板类，ac(5)定义模板类的对象cout<<"填充一个字符数组";ac.fill_Array();cout<<"数组的内容是:";ac.disp_Array();Array<double> ad(3);cout<<"填充一个双精度数组";ad.fill_Array();cout<<"数组内容是:";ad.disp_Array();return 0;}
