invalid conversion from 'const ... ' to '...'

[johnny45634]

Hi everyone,

I keep getting errors from the following code:

         int orgCount, newCount;
         wordcount *wrdPtr;
         wrd = words.find(*wrd);//error: invalid conversion from 'const wordcount*' to 'wordcount*'

         orgCount = &wrdPtr.getCount;//error: request for member 'getCount' in 'wrdPtr', which is of non-class type 'wordcount*'
         newCount = orgCount + 1; 
         words.erase(*wrd);

         wordcount *exwrd = new wordcount(tempWord, newCount);
         words.insert(*exwrd);

I am trying to get the address by calling words.find(*wrd), then get the count number of that object from the address.
wordcound is the class name.

here is my getCount():

    const int getCount() const
    {
      return count;
    }

and find(), which can not be changed in any ways:

      const dataType* find(const dataType &findData) const 
      {
         // this function looks for findData in the tree.
	     // If it finds the data it will return the address of the data 
	     // in the tree. otherwise it will return NULL
	     
         if (root == NULL) return NULL;
         else return root->find(findData);
      }

Thanks for the help.

1st error: Your find function returns constant pointer. You cannot assign const pointer to non-const one.

2nd error: you are trying to call method of address of pointer (pointer to pointer). Maybe you wanted wrdPtr->getCount()?

Do you have any suggestions of how I can fix this?
I need to get the address from find function, then use that address to get the count number.

Thanks for your help.

find function already returns address to found element.
I suggest to do something like

const wordcount *wrdPtr;
wrdPtr = words.find(/*What to find*/);
orgCount = wrdPtr->getCount();

Thanks for the advice, but now I get:

wordcount *wrdPtr;
wrdPtr = words.find(*wrd);
// error: invalid conversion from 'const wordcount*' to 'wordcount*'
orgCount = wrdPtr->getCount;
//error: argument of type 'int (wordcount::)()' does not match 'int'

I have missed const in my example. Fixed now.
3rd line. Answer, how the function is called? What is the difference between mine and yours line?

Look at line 1 of MiiNiPaa's example and line 1 of your example

Oh... my bad.

Thanks for the help guys!!!
