"Class" does not name a type error

[bm2112]

I am creating a templated ArrayList class and I have the functions written but I cannot get it to compile. My arraylist.h file includes my arraylist.hpp right before the #endif. My arraylist.hpp gets the "'ArrayList' does not name a type" error for the destructor, copy constructor, and operator =. The other functions get errors saying "expected initalizer before '<' token. I have looked through a ton of forums covering the same issue but none of their solutions worked for me. Here is my code:


<
using namespace std;

//Destructor
template <typename T>
ArrayList<T>::~ArrayList()
{
delete[] m_data;
m_data = NULL;
m_size = 0;
m_max = 0;
}

//Equals operator
template <typename T>
ArrayList<T>& ArrayList<T>::operator=(const ArrayList<T>& rhs)
{
delete[] m_data;
m_data = NULL;
m_size = rhs.m_size;
m_max = rhs.m_max;
m_errobj = rhs.m_errobj;
m_data = new T[m_size];
for(int k = 0; k < m_size; k++)
m_data[k] = rhs.m_data[k];
return *this;
}

//Copy constructor
template<typename T>
ArrayList<T>::ArrayList(const ArrayList<T>& cpy)
{
m_size = cpy.m_size;
m_max = cpy.m_max;
m_errobj = cpy.m_errobj;
for(int k = 0; k < m_size; k++)
m_data[k] = cpy.m_data[k];
}

//Returns size of ArrayList
template<typename T>
int ArrayList<T>::size() const
{
return m_size;
}

//Returns first element in ArrayList
template<typename T>
const T& ArrayList<T>::first() const
{
if(m_size > 0)
return m_data[0];
else
return m_errobj;
}

//Returns r/w reference to element at position i
template<typename T>
T& ArrayList<T>::operator[](int i)
{
return m_data[i];
}

//Returns read-only reference to element at position i
template<typename T>
const T& ArrayList<T>::operator[](int i) const
{
return m_data[i];
}

//Returns the index of element T
template<typename T>
int ArrayList<T>::find(const T& x)
{
for(int k = 0; k < m_size; k++)
{
if(x == m_data[k])
return k;
}
return -1;
}

//Clears all values in the ArrayList as well as size and max values
template<typename T>
void ArrayList<T>::clear()
{
delete[] m_data;
m_data = NULL;
m_size = 0;
m_max = 0;
return;
}

//Puts value x at the end of ArrayList
template<typename T>
void ArrayList<T>::insert_back(const T& x)
{
if(m_size == m_max)
{
T* tmp = new T[m_max*2];
m_max = m_max * 2;

for(int k = 0; k < m_size; k++)
{
tmp[k] = m_data[k];
delete [] m_data;
m_data = tmp;
}

m_data[m_size] = x;
m_size++;
}
}

//Inserts the element x at the index i in the ArrayList
template<typename T>
void ArrayList<T>::insert(const T& x, int i)
{
if(i < 0 || i > m_size)
cout << "Sorry, that index is invalid.";
if(m_size == m_max)
{
T* tmp = new T[m_max*2];
m_max = m_max * 2;

for(int k = 0; k < m_size; k++)
{
tmp[k] = m_data[k];
delete [] m_data;
m_data = tmp;
}

for(int k = m_size; k > i; k--)
m_data[k] = m_data[k-1];

m_data[i] = x;
m_size++;
}
}

//Removes the element at index i in the ArrayList
template<typename T>
void ArrayList<T>::remove(int i)
{
if(i < 0 || i >= m_size)
cout << "Sorry, that index is invalid";
for(int k = i; k < m_size-1; k++)
m_data[k] = m_data[k+1];
m_size--;
return;
}

//Swaps the elements at indexes i and k
template<typename T>
void ArrayList<T>::swap(int i, int k)
{
T temp = m_data[i];
m_data[i] = m_data[k];
m_data[k] = temp;
return;
}

//Adds alist to the end of the current ArrayList
template<typename T>
void ArrayList<T>::append(const ArrayList<T>& alist)
{
int oldSize = m_size;
m_size+= alist.m_size;
for(int k = 0; k < alist.m_size; k++)
m_data[k+oldSize-1] = alist.m_data[k];
return;
}

//Removes all duplicate elements in the ArrayList
template<typename T>
void ArrayList<T>::purge()
{
for(int j = 0; j < m_size; j++)

I think you'll get a practical response if you do the following rather than expect people to wade through all this stuff:

1. Use code tags so that your code appears with line numbers etc - like the purple boxes you see everywhere.
2. Give us enough code so we can run/compile the program. Presumably you have a test file? If so please include that too.
3. Show us a copy of the error messages you got and the the line numbers. It helps us to help you :)

The code you posted is wrapped with < and > is that in your actual code?

we need to see your class declaration also.

And as kemort says, use the code tags to highlight code
Its the <> button to the right of the text editor while typing.

As the others have said, there's not enough here to compile.
We need your class declaration.

I don't know if the < > bracketing your code was an attempt at using code tags.
You can find instructions on how to use code tags here:

Hint: You can edit your post, highlight your code and press the <> formatting button.
