Cannot use any List operations(using Ubuntu)

Hello everyone, I'm trying to construct a header class call Shopper.h, and inside the class I created a list and trying to manipulate using list operation, but every time I try to use any list operation, it doesn't comply. But when i used list operations on cpp file, it works.

Code:

---

#include <string>
#include <iostream>
#include <list>
using namespace std;

class Shopper{

public:
  Shopper(string &n,string &p,list<string> L)
    {
      name = n;
      pro = p;
      shopList = L;
    {
   
   

  void delShop()
  {
    list<Shopper>::iterator i;
    i = shopList.begin();
    i =  shopList.erase(i);
  }

//Return the first shop on the list
string firstShop()
{
  return shopList.front();
}

string getPro()
{
  return pro;
}

string getName()
{
  return name;
}

private:
 string name;
  string pro;
  list<string> shopList;
};

If you set that iterator in the constructor, then add things to the list and try to use the iterator, it probably won't work (esp if you set it before there was anything in the list). Iterators are intended to be set and used right away -- you can't save them, work with the data structure for a while, and then expect them to serve much of a purpose unless you reset them.

What does that mean? Do you get a compiler error? Does the program fail? Does it crash?

Sorry, I meant complier error.

Code:

---

error: no match for ‘operator=’ in ‘((Shopper*)this)->Shopper::it1 = ((Shopper*)this)->Shopper::shopList.std::list<_Tp, _Alloc>::begin [with _Tp = std::basic_string<char, std::char_traits<char>, std::allocator<char> >, _Alloc = std::allocator<std::basic_string<char, std::char_traits<char>, std::allocator<char> > >]()’

Shopper.h: In function ‘void delShop(int)’:
Shopper.h:24: error: ‘shopList’ was not declared in this scope.

shopList is declared as a list of string, not a list of Shopper.
Besides, all you need is:

Code:

---

void delShop()
{
    shopList.pop_front();
}

Make sure you learn about const-correctness and constructor initialisation lists also.

Problem solved, Thank you so much
Yes, i am trying to learn c++ and this is my first C++ program. Thank you for your help
