array.h

用template实现一维数组的数据结构。

#ifndef _ARRAY_H_
#define _ARRAY_H_

#include <iostream>
#include <stdlib.h>
using namespace std;

#define DefaultSize 10
template < class Type>
class Array {
public:
    Array( int Size = DefaultSize );
    Array( const Array <Type> &x );
    ~Array() { destroy(); }
    Array<Type> &operator = ( const Array<Type> &A);
    Type & operator [] ( int i );
//    Array<Type> operator Type * ()const { return elements; }
    int Length() const { return ArraySize; }
    void ReSize ( int sz);
    friend ostream& operator <<(ostream& , Array<Type>&);
//    void Print();
private:
    Type *elements;
    int ArraySize;
    void getArray();
    void destroy(){delete[] elements;};
    void copyFrom(const Array<Type> &x);
};
