It was same as for linked list above - To have input from user instead of predefined list. But I managed to do it

Could you also help me in user input for STL list?

#include<iostream>
#include<list> // for list operations
using namespace std;

int main()
{
// initializing list of integers
list<int> list1={10,15,20,25,30,35};

// declaring list iterators
list<int>::iterator it = list1.begin();
list<int>::iterator it1 = list1.begin();

// incrementing the positions of iterators
advance(it,2);
advance(it1,5);

// printing original list
cout << "The original list is : ";
for (list<int>::iterator i=list1.begin(); i!=list1.end(); i++)
cout << *i << " ";

cout << endl;

// using erase() to erase single element
// erases 20
list1.erase(it);

// list after deletion 1 element
cout << "The list after deleting 1 element using erase() : ";
for (list<int>::iterator i=list1.begin(); i!=list1.end(); i++)
cout << *i << " ";

cout << endl;

it = list1.begin();

// incrementing the positions of iterators
advance(it,2);

// using erase() to erase multiple elements
// erases 25,30
list1.erase(it,it1);

// list after deletion of multiple elements
cout << "The list after deleting multiple elements using erase() : ";
for (list<int>::iterator i=list1.begin(); i!=list1.end(); i++)
cout << *i << " ";

cout << endl;


}

many thanks

Do I need to write this?
