Overloading operator = error

Question

Im trying to create a stack but im receiving errors with overloading my = operator. The stack is of type template. Heres the code

template <typename T>
T& ::stack& operator =(const stack& other)
{
    if (this == &other) return *this;

    copy(other.stack1[0], other.stack1[other.size], stack1[0]);
    return *this;
}

Any help will be appreciated. Thanks

Answer 1

Please try the below signature

template <typename T>
stack<T>& stack<T>:: operator =(const stack<T>& other)

Answer 2

Try:

template <typename T>
stack<T>& stack<T>::operator =(const stack& other)
{
    if (this == &other) return *this;

    copy(other.stack1[0], other.stack1[other.size], stack1[0]);
    return *this;
}
