i am trying to create a program that shows details of 40 different hills. he dteails must include hieght and distance from home. i am trying to show tge details in order of height from smallest to highest but i cant get them in order here is all of my code

```
#include <iostream>
using namespace std;
struct Node{ //a structure that can be
int data; //thought of as a simple class
Node *link; //All fields are public
};
class LinkedList{
public:
Node *head; //pointer to the first node
Node *last; //pointer to the last node
int count; //number of nodes
int index;
LinkedList(); //default constructor
//first = NULL
//last = NULL
//count = 0
void insertFirstNode(int newinfo); // inserts a node
//at the start of the list
void insertLastNode(int newinfo); // inserts a node
//at the end of the list
int getNodeCount(); //returns the number of nodes
Node* getFirst(); //returns the pointer to the
//the first node - the value of "head"
void displayData();
};
#include "coursework.h"
#include <iostream>
#include <cstdlib>
#include <ctime>
using namespace std;
void insertionSort(LinkedList *ll){
Node *current = ll->head->link; //2 variables used for searching
Node *trailCurrent = ll->head; //through the linked list
//now use them to find how much of the list is currently
//in order, by starting at the head and continuing so long
//as the data in one node is greater than that in the previous node
while(current->data > trailCurrent->data){
trailCurrent = current;
current = current->link;
}
Node *lastInOrder = trailCurrent; //place the information obtained
Node *firstOutOfOrder = current; //above into these variables
//now start at the end of the ordered part of the list and deal one
//at a time with the unordered nodes
while(lastInOrder->link != NULL){
//first special case - the next node must go to the start of the list
if(lastInOrder->data < firstOutOfOrder->data){
lastInOrder = firstOutOfOrder;
firstOutOfOrder = firstOutOfOrder->link; //see below - repeat
} //but no harm done
else{
//second special case - the first out of order node is greater
//than any in the ordered list and stays where it is, but the pointers
//"lastInOrder" & "firstOutOfOrder" must now be made to point to
//the nodes along one
if(ll->head->data > firstOutOfOrder->data){
lastInOrder->link = firstOutOfOrder->link;
firstOutOfOrder->link = ll->head;
ll->head = firstOutOfOrder;
}
//otherwise go through the linked list to find where the
//first out of order node goes and rearrange the links
//accordingly
else{
current = ll->head->link;
trailCurrent = ll->head;
while(current->data < firstOutOfOrder->data){
trailCurrent = current;
current = current->link;
}
lastInOrder->link = firstOutOfOrder->link;
firstOutOfOrder->link = current;
trailCurrent->link = firstOutOfOrder;
}
firstOutOfOrder = lastInOrder->link; //see above - repeat
}
}
}
