نمونه برنامه شی گرا

[imdeveloper]

سلام
خسته نباشید
من دارم یه برنامه شی گرا مینویسم در واقع اول حالت ساخت یافته اون رو نوشتم و حالا قصد دارم شی گرا بنویسم اما خب توی یه سری جاها به مشکلی خوردم
ممنون میشم اگر نمونه برنامه شی گرایی که یه سری اطلاعات رو از ورودی بگیره و توی آرایه و یا وکتور و یا حتی فایل ذخیره کنه رو اگه دارین معرفی کنین

به عنوان نمونه میتونید این کد رو مطالعه کنید که به صورت ساده و با استفاده از اشاره گر ها یک صف (queue) میسازه و داده ها رو در اون ذخیره میکنه.
#include <iostream>using namespace std;
struct Node {
int data;
Node* next;
};
class Queue {
struct Node* head,* tail;
public:
Queue() {
head = tail = NULL;
}
void enQueue();
void deQueue();
void displayQueue();
void menu();
int elem;
int choice;
};
void Queue::enQueue() {
cout << "Enter your element to be inserted the queue:" << endl;
cin >> elem;
Node* pointer = new Node;
pointer -> data = elem;
pointer -> next = NULL;
if(head == NULL) {
head = pointer;
}
else
tail -> next = pointer;
tail = pointer;
cout << "Element has been inserted in the queue!" << endl;
}
void Queue::deQueue() {
if(head == NULL){
cout << "Queue is empty!" << endl;
}
Node* temp = head;
head = head -> next;
delete temp;
}
void Queue::displayQueue() {
Node* pointer1 = head;
if(head == NULL) {
cout << "Queue is empty!" << endl;
}
else
cout << "Elements of your QUEUE!" << endl;
while (pointer1 != NULL) {
cout << pointer1 -> data << endl;
pointer1 = pointer1 -> next;
}
cout << "End" << endl;
}
void Queue::menu() {
while(1)
{
cout<<"================================================== ============="<<"\n";
cout<<" MENU - QUEUE(FIFO - First In First Out) "<<"\n";
cout<<"================================================== ============="<<"\n";

switch(choice)
