error C2664: 'searchTree' : cannot convert parameter 2 from 'const char *' to 'char'

[slizorn]

well the error i get is the title above:
error C2664: 'searchTree' : cannot convert parameter 2 from 'const char *' to 'char'

error is form this line

searchTree(treeObj->root ,data1.c_str());
 

i have also attached searchTree below for yr reference

Tree<char> *treeObj = NULL;
TreeNode<char> *treeNodeObj = NULL;
 
TreeNode<char>* searchTree(TreeNode<char> *cur, char nodeToAdd)
{
    if(cur == NULL) 
    {
        return NULL;
    }
    if(cur->IsSameNode(nodeToAdd))
    {
        return cur;
    }
    searchTree(cur->getLeft(), nodeToAdd);
    searchTree(cur->getRight(), nodeToAdd);
}
 

could anyone help me with this problem..?
well at first i get the problem that it can convert from char to string.. thats y i added the .c_str() but now it gives me the new error above..
any help is appreciated..
I will check forum every 5 mins .. so i will reply quick..
Thanks in advance :)

what is 'data1' ? How did you declare it?

other than that, it LOOKS like you are attempting to make 'data1' into a string, and then pass it into a function looking for a char ... that's just not gonna happen ... why are you passing some sort of string into a char argument?

oops my bad..
i declared it as string..

void handleOneLine(string string1)
{
    char * cstr, *p;
    int counter;
    string str (string1);
    string data1, data2, data3;
 
    cstr = new char [str.size()+1];
    strcpy (cstr, str.c_str());
 
    // cstr now contains a c-string copy of str
 
    int count = 0;
    p=strtok (cstr,",");
    count++;
    while (p!=NULL)
    {
        p=strtok(NULL,",");
        if( count == 1 )
        {            
            data1.append(p);
            searchTree(treeObj->root ,data1.c_str());
        }
        else if( count == 2 )
        {
            data2.append(p);
//            treeNodeObj->setLeft(data2);
        }
        else if( count == 3 )
        {
            data3.append(p);
//            treeNodeObj->setRight(data3);
        }
        count++;
        if( count == 3 )
            break;
    }
 
    delete[] cstr; 
}

I edited my previous post, not sure if you saw ...

done that.. that problem is solved.

thanks for yr help :)
