求大神帮忙看下C++数组类模版到底有什么错误哦
#include <iostream>using namespace std;
template <class T>
class Array
{
private:
T* alist;
int size = 0;
public:
Array(int sz);
Array(const Array<T>& a);
~Array();
void display();
T& operator[](int i);
Array<T>& operator =(Array<T>& a);
operator T*(void)const;
};
template <class T>
Array<T>::Array(int sz)
{
if (sz <= 0)
{
cout << "Array size error." << endl;
exit(1);
}
else
{
size = sz;
alist = new T;
if (alist = NULL)
{
cout << "Array memory allocation error." << endl;
exit(1);
}
}
}
template <class T>
Array<T>::Array(const Array<T>& a)
{
size = a.size;
list = new T;
if (list = NULL)
{
cout << "Array memory allocation error." << endl;
exit(1);
}
int n = size;
T* pointer1 = list;
T* pointer2 = a.alist;
while (n--)
{
*pointer1++ = *pointer2++;
}
}
template <class T>
Array<T>::~Array()
{
delete[] alist;
size = 0;
}
template <class T>
void Array<T>::display()
{
for (int i = 0; i < size; i++)
{
cout << setw(5) << *(alist + i);
}
cout << endl;
}
template <class T>
T& Array<T>::operator[](int i)
{
if (i < 0 || i > size - 1)
{
cout << "Array[]size error." << endl;
exit(1);
}
return alist;
}
template <class T>

大致读了一下，你的代码脉络不是很清晰
有几个明显的错误，比如：private中的size不能进行赋值
