cannot convert parameter 2 from 'char *' to 'const char &'

[Saggio]

Okay, this error is rather annoying, as I can not progress with my program without resolving it.

It is an e-mail checker, and this part is extracting the domains (we previously did it with arrays) using a user-defined template vector class (using char as the type). As of now I'm completely stumped since most of the code was pseudo code from my professor, so I know I'm at least on the right track...

class EmailDomain
{
   public:
      EmailDomain()
      {
          Name = DynamicString::DynamicString();
          SubdomainCount = 0;
      }
   
   public:
      DynamicString Name;

      Vector<char> Subdomain;
      //EmailSubdomain Subdomain[MAX_SUBDOMAINS];
      int SubdomainCount;
      EmailTld Tld;

   public:
      bool Parse();
      bool IsValid();
};

// Extract subdomains
   do
   {
      int nextPosition = Name.IndexOf('.', startPosition);
      Subdomain.BoostCapacity(1);
      if ( nextPosition != -1 )
      {
          Name.Copy(Name.Buffer, Subdomain.Buffer, startPosition + 1, nextPosition - startPosition);
          Subdomain.InsertAt( Subdomain.Size, Subdomain.Buffer );
      }
      else
          Name.Copy(Name.Buffer, Tld.Name.Buffer, startPosition + 1, Name.Size);
      startPosition = nextPosition + 1;

   } while ( startPosition != 0 );

Buffer is of type T* (so in this case....char*) in the vector class

And here is the InsertAt function from the Vector class

void InsertAt(int index, const T& value)
    {
        
        if ( index > Size || index < 0 )
            throw "Vector::InserAt() index out of range";

        // Exceeding current capacity?
        BoostCapacity(1);

        // Make room for the new intacter
        MoveBy(index, 1);
        Size++;

        // Set the value
        Buffer[index] = value;
    }

The error occurs on the line that is bold, italicized and underlined

If you need anything else, just ask me. Thanks!

Is InsertAt a member function? I assume it must be from the way you call it, but the definition is that of a non-member (and non-template). I would expect it to be:

template <class T>
void Vector<T>::InsertAt(int index, const T& value)
{
  //...
}

If that were the case, assuming T = char, then you're trying to pass a pointer to char to a function that expects a reference to char.

Yes, it's a member of the Vector class.


The only reason why the function header doesn't look right is because it's currently defined in the Vector.h class...I haven't created the .cpp implementation file for it yet..I want to get it working first

You probably want Subdomains to be a Vector<string> or something similar, since a char holds only a single character.
