modifyByValue vs modifyByReference

[LB]

They don't have to. They can be created inside any scope - that includes outside functions, inside functions, inside classes, inside a class' member function, inside a for loop, etc.

L B I NEED TO CREATE A NODE CLASS THAT STORES AN INTEGER.

[LB]

class Node
{
    int x;
};

Unless you get more specific I can't really help.

[viliml]

plz stop using caps

[Napster12]

Thanks LB,
but the first thing i have to do is to create a List class with the following two interface:
List::addItem //add an item to the list
List::getTheLargestValue //find the largest value stored in the list

the largest value among the integers i want to store in the list
the node i want to create is to store those integers

[LB]

What do you have so far?

[Napster12]

class Node {

Node*nextNode;
int itemNumber;

Node* getNextNode () {return nextNode;}
cout<<"The largest value is: " << Largest Node >>printValue();

};


int main (){
List aList;

Next*largestNode = aList*getLargestNode ();

}

this is what i get so far
i'm not sure i'm on the right track

[LB]

getNextNode() needs to be public.
that cout statement doesn't belong in the direct scope of a class, not does the function T &printValue(void); exist.
List class does not exist.
List getLargestNode(void) does not exist
Class Next does not exist
Next *operator*(const List &, const List &) does not exist

[Napster12]

i'm really confused now
can you write a sample?

[LB]

class SimpList
{
    struct Node
    {
        Node *next;
        double value;
        Node() : next(0) {}
    } *head;
public:
    SimpList() : head(0) {}
    void Add(double v)
    {
        if(!head)
        {
            head = new Node;
            head->value = v;
            return;
        }
        Node *p = head;
        while(p->next) p = p->next;
        p->next = new Node;
        p->next->value = v;
    }
    ~SimpList()
    {
        if(!head) return;
        Node *p = head;
        while(p->next)
        {
            Node *t = p;
            p = p->next;
            delete t;
        }
        delete p;
    }
};

Here is a sample. However, it is not necessarily what your assignment wants.

[Napster12]

Using inheritance, i have a base class and two derived classes. One derived class is to insert an integer, the other derived class is to insert a character. I need help writing this code.

[LB]

What do you mean by insert?

[Napster12]

in this context insert means add an integer, add a character to a list

[LB]

OK, what list will the integer and character be added to?

[Napster12]

the class List as the base class

[LB]

That assignment doesn't make sense.

[Napster12]

Here is the model of what I'm talking about:

class List {
public:
.............
.............

};

class intNode: public List
public:
{
........
........
};

class charNode: public List
public:
{
.............
.............

};
