Easier Way To Do a Linked List?
This is how my teacher explained to use how to do a linked list.

Code:

```#include <iostream>                        #include <cstdlib>                        #include <math.h> #include <fstream> #include <string> using namespace std; struct Node{     string parts;     int ID;        int date;     float price;     Node *next;          Node(); }; Node::Node(){ next=NULL; } void Insert(Node *&Front,Node *&Rear, string n_parts, int date, int n_Id, float n_price, int count){     Node *n_Info = new Node();  // dynamically allocation a node       n_Info->parts = n_parts;    // enter info onto this node's data fields     n_Info->date = date;     n_Info->price = n_price;     n_Info->ID = n_Id;     if(count ==0){                Front = Rear = n_Info;     }     else if(count > 0){         Rear->next = n_Info;            // Rear = n_Info;      // this statement acts the same as next line         Rear = Rear -> next;     } } void Flush(Node *&Front,Node *&Rear, int L_size){     Node *temp_node = Front;     for(int i =0; i<L_size; i++){         Front = Front->next;         delete temp_node;         temp_node=Front;     } } int main(){         Node *Front = NULL;     Node *Rear = NULL;                              int L_size = 0;                                ifstream in("a7.txt");             char temp[100];     string temp_parts;     int temp_ID;     int temp_date;     float temp_price;     while(in.peek() != EOF){         in.getline(temp, 100);         temp_parts = temp;         in.getline(temp, 100);         temp_ID = atoi(temp);                 in.getline(temp, 100);         temp_date = atoi(temp);                      in.getline(temp, 100);         temp_price = atof(temp);         in.getline(temp, 100);         Insert(Front, Rear, temp_parts, temp_date, temp_ID, temp_price, L_size);                 L_size++;     }       cout << "Total number of entries: " << L_size << endl;         Flush(Front, Rear, L_size);                       return 0;                    }```
I was wondering if there was an easier way than this that does the same thing? Also how do I access things in the linked list?

If you're learning about the internals of a linked list, and the concept of a linked list, probably not.

If you're writing normal code, then you should be using std::list
