Ok, so I am befuddled. Each individual file compile fine, no errors. When I compile all together and create an executable, no errors. But, when I run the program, I am getting an error. I have it narrowed down to a problem with my void LinkedList::insert(const ElementType &dataValue) but I have looked at it too many time to figure out what's wrong. The main concept is that a new node will be inserted in a sorted order based on the key of a struct. The linked list is sorted alphabetically. Also attached is a sample of the data being read in.
/*~~~linkedlist.h~~~~*/
#include <iostream>
#include <string>
using namespace std;
typedef struct Articles ElementType;
typedef std::string KeyType;
struct Articles
{
string key;
string name;
string title;
};
class LinkedList
{
private:
class Node
{
public:
ElementType data;
Node * next;
Node(ElementType dataValue){
data = dataValue;
next = NULL;
}
};
typedef Node * NodePointer;
Node *find (const KeyType &key);
NodePointer first;
int mySize;
int index;
public:
LinkedList();
void insert (const ElementType &item);
bool find (const KeyType &key, ElementType &item);
bool erase (const KeyType &key);
};
bool operator==(const ElementType &e1, const KeyType &key);
bool operator>=(const ElementType &e1, const KeyType &key);/*~~~linkedlist.cpp~~~~*/
#include <iostream>
using namespace std;
#include "linkedlist.h"
LinkedList::LinkedList()
{
first = NULL;
mySize = 0;
}
void LinkedList::insert(const ElementType &dataValue)
{
NodePointer nPtr = new Node(dataValue);
NodePointer predPtr = first;
if (first->next == NULL)
{
nPtr->next = first;
first = nPtr;
}
else
{
while ((dataValue.key) >= predPtr->data.key)
{
predPtr=predPtr->next;
}
if ((dataValue.key) == predPtr->next->data.key)
{
nPtr->next = predPtr->next;
predPtr->next = nPtr;
}
}
}
bool LinkedList::find(const KeyType &key, ElementType &item)
{
}
bool LinkedList::erase(const KeyType &key)
{
}
bool operator==(const ElementType &e1, const KeyType &key)
{
if (e1.key == key)
return true;
else
return false;
}
bool operator>=(const ElementType &e1, const KeyType &key)
{
if (e1.key >= key)
return true;
else
return false;
}/*~~~program2.cpp~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
| A driver file which plays a game of Tic Tac Toe with two |
| players. The program incorporates 2 classes (and header |
| files for each): Tictactoe and Player. Tictactoe handles |
| the displayBoard(), setValue(), and getStatus() functions. |
| The Player class handles getName(), getIndex(), and |
| getMove() functions. Definition of the functions are in |
| their corresponding .cpp/.h files. |
| Game play consists of receiving a player's name then |
| determining which player goes first. The players, starting |
| with the first player, will be prompted to enter a position |
| which will be checked for whether: the space is out of the |
| scope and whether the space is already occupied, and if |
| neither is the case, the spot will be marked with the player's |
| mark (X or O). Then the program will check if there is a win, |
| a tie, or other(results in continuing game play). A win can |
| be from either player and is checked after each player's "turn." |
| The game board is displayed at the beginning (with no X's or O's) |
| and after each player's turn. |
