How to delete all values in the linked list

[depecheSoul]

Hello.

I have made this program for linked list, but i have one problem with it. I want to make a function that will delete all same values I inuput in the list.

Example: if user inputs 5 I want to delete all 5 for the list.

I have tried doing this with the loop inside regular function that erase single value.

This is funnction that erases single value:

void list::Delete (int a)
{
    node *temp=head;

    if (temp==NULL)
        return ;

    if (temp->getNext()==NULL)
    {

        delete temp;
        head=NULL;
    }
    else
    {
        node *prev;

        do
            {
                if (temp->getBroj()==a)
                    break;

                prev=temp;
                temp=temp->getNext();
            }while (temp!=NULL);

            prev->setNext(temp->getNext());

       }
}

This is my attempt to make function:

else
    {
        bool change=false;

        node *prev;

        do
        {
            change=false;
            do
            {
                if (temp->getBroj()==a)
                {
                    change=true;
                    break;
                }

                prev=temp;
                temp=temp->getNext();
            }while (temp!=NULL);

            prev->setNext(temp->getNext());

        }while (!change);
    }

Thank you
