MHB Deleting Middle Node in Linked List

[needOfHelpCMath]

how would be able to delete the middle D: so far I deleted the last two, which i do not want.

These are my values in the nodes: 9->1->2->4->10->6->8

//part F will tranverse in the middle and delete the middle
 void insertMiddle(Node *nn) {
	while(nn->next->next->next != NULL) {
		nn = nn->next;	
	}
		delete nn->next;
		nn->next = NULL;
        }
    
    int main() {
    // part A
   Node *a; 
   a = new Node(1,NULL);
   
   
   Node *b;
   b = new Node(2,NULL);
   
   Node *c;
   c = new Node(4,NULL);
  
   
   Node *d;
   d = new Node(6,NULL);
   
   
   Node *e;
   e = new Node(8,NULL);
  
   Node *f;
   f = new Node(9,NULL); // insert at the beginning of Node *a;
   
   Node *g;
   g = new Node(10,NULL); // insert in the middle
   
   f->next = a;
   a->next = b;
   b->next = c;
   c->next = d;
   d->next = e;
   
   c->next = g;
   g->next = d;

/ /part F
   list.insertMiddle(f);
   cout << endl;
   list.print(f);

   return 0;
	}

I am not sure what you are saying here. Are you given that the "linked list" includes exactly 7 items and you want to remove the middle, i.e. fourth, item?

Also you have a comment that says "part F will tranverse (I think you mean "traverse") in the middle and delete the middle" but you have named the subroutine "insertMiddle"/ Are you inserting or deleting?

sorry i wasnt clear..sorry ill upload the whole source code and sorry for mis-information; the insertToMiddle is my function to find the middle and delete the middle

This is the source code:

#include<iostream>

using namespace std;

class Node {
      
      public:
             int  Nodedata;
             Node *next;
             Node() {next =  NULL; Nodedata = 0;}
             
             Node(int data, Node *nextNode) { //overloaded constructor
             Nodedata = data;
             next = nextNode;
          }
      
      
};
 // traverse printing all the elements
class SLL {
	
	public:
		Node *front;
		// part D Traverse the SLL and print all the elements out
	void print(Node *nn) {
		while (nn !=  NULL) {
			cout << nn->Nodedata << " ";
			nn = nn->next;
		}
		
	}
	 // part E delete last node
	 void deleteback(Node *nn) {
	 	while (nn->next->next != NULL) {
	 		nn = nn->next;
		 }
		 
		 delete nn->next;
		 nn->next = NULL;
		 
	}
		//part F will tranverse in the middle and delete the middle
	 void insertMiddle(Node *nn) {
		while(nn->next->next->next != NULL) {
		nn = nn->next;	
	}
		delete nn->next;
		nn->next = NULL;
	}
	
};

int main() {
    // part A
   Node *a; 
   a = new Node(1,NULL);
   
   
   Node *b;
   b = new Node(2,NULL);
   
   Node *c;
   c = new Node(4,NULL);
  
   
   Node *d;
   d = new Node(6,NULL);
   
   
   Node *e;
   e = new Node(8,NULL);
  
   Node *f;
   f = new Node(9,NULL); // insert at the beginning of Node *a;
   
   Node *g;
   g = new Node(10,NULL); // insert in the middle
   
   f->next = a;
   a->next = b;
   b->next = c;
   c->next = d;
   d->next = e;
   
   c->next = g;
   g->next = d;
   
   SLL list; // object of the class SLL and part D
   list.print(f);
   
   // part E deleting the last element
   list.deleteback(f);
   cout << endl;
   list.print(f);
   
   // part F
   list.insertMiddle(f);
   cout << endl;
   list.print(f);
   
   return 0;
