Template class assignment operator

Question

I have a problem with a template class I named "DynamicArray". The only problem that I have is when I define my assignment operator. it gives me two different errors

1) the first error it gives me is

DynamicArray& says "argument list for class template "DynamicArray" is missging"

2) the second error is

DynamicArray::operator= says "template argument list must match the parameter list"

this is my program:

DynamicArray.h

#pragma once
#include <iostream>

using namespace std;

template<typename T>
class DynamicArray
{
public:
    DynamicArray();
    DynamicArray(const DynamicArray &d);
    DynamicArray& operator=(const DynamicArray &d);
    ~DynamicArray();
};

template<typename T>
DynamicArray<T>::DynamicArray()
{

}

template<typename T>
DynamicArray<T>::DynamicArray(const DynamicArray &d)
{

}

template<typename T>
DynamicArray& DynamicArray<T>::operator=(const DynamicArray &d)
{

}

template<typename T>
DynamicArray<T>::~DynamicArray()
{

}

I have looked at multiple examples and can't figure out why I have this problem.

Can anyone tell me what I am doing wrong here?

Answer 1

1. Put the complete template in the header file as Neil suggested via the link to Why can templates only be implemented in the header file?.
2. The return value from operator= should be DynamicArray<T>&
