Double Linked List using cpp file

this is what i have so far but I do not think that what i have is compiling correctly, i am trying to declare lists and i thought that is what i did. i have so many compiling errors, and i tried fixing them. but not working for me, any help?

what is dnode? Where is it declared ?

[nmaillet]

Where are the declarations of dnode and the include function? Other than that, quickly looking through the code: if(val1 < val) would not work, since there is no declaration for it. I am assuming you meant something like if(val1 < p->val) Also the statement *p->next; would not do anything. It would simply give the structure pointed to by the structure *p, but would not assign it to anything. p = p->next; would do that.

         {
             p = p ->next;//move the pointer forward.
         }

         else{
             include(p, val);//else insert the new value now
         }
     }

     dnode <double> *p2 = listB -> next; //points to the node following the header of listB

//Nested for loop to read in up to val2 # of doubles

    for (int i = 0; i < val2; i++)
    {

     for (int j = 0; j < i; j++)
     {
         if(val2 < p->val)//the value at the second pointer is less then the new value
         {
             p2 = p2 ->next;//move the pointer forward.
         }

         else{
             include(p2, val);//else insert the new value now
         }
     }

    return 0;
}

in order to declare the dnode and include functions:

it would be near the top? but wouldnt it be like dnode<double> = listA, listB;

The code you originally posted does not include that header file. You need to add it after <fstream> then recompile to see how many errors disappear.
