Print pointers

ok so i am trying to print an int that is in a point but it wont let me, this is what i have...

Code:

---

void linkedQueue::addRear(el_t newNum)
{   
    Node *rear;
    Node *front;
   
    if(count==0)
    {
          rear=new Node;
          rear->elem=newNum;
          front=rear;
    }
    else
    {
          rear->next=new Node;
          rear=rear->next;
          rear->elem=newNum;
    }

    count++;

void linkedQueue::displayAll()
{
    cout<<rear->elem;
}
}

---

i kno that will not print the whoe list, but im trying to start by just printing one and i cant!!! lol why is this wrong?

What is the definition of Node? What is the problem that you face? A compile error? Runtime output not what you expected? How does it not work?

Code:

---

struct Node
{
      int elem;
      Node *next;
};

---

and all im trying to do is print the int at rear->elem, but when i do it says

Quote:

---

'elem' has not been declared

Well, I note that you are using rear as a member variable in displayAll(), but you also declared a local Node* variable named rear in addRear(). Are you sure you have a Node* member variable named rear, and that the local variable rear in addRear() is really what you want?

im trying to make a linked list that these functions can manipulate. so i have a list and addRear() adds to the rear, displayAll() shows everything in the list, etc.

I guessed as much... the problem should just be that you are using local variables in your member functions but you think you are using member variables.

ya i suspected that (complete n00b if you couldnt tell already lol)

Code:

---

#ifndef linkedQueue_H
#define linkedQueue_H

#include<iostream>

using namespace std;

struct Node
{
      int elem;
      Node *next;
};

class linkedQueue
{ 
      typedef int el_t;
       
      public:
            linkedQueue();
            ~linkedQueue();
           
            void addRear(el_t newNum);
            void deleteFront(el_t oldNum);
           
            bool isEmpty();
            int getSize();
            void displayAll();
           
      private:
              int *front,*rear,count;
              void queueError(char* mesg);
};

#endif

is what if have now, and when i put in 'Node *rear;' it gives me all sorts of crap for it. isnt that how i would allow all the functions to use it?

Code:

---

int *front,*rear,count;

---

You declared them as int* instead of Node*.

ooooooooo wow, that would make a difference. thanks a lot
