program Linked List: modify the following program to make a node containing data values of int, char, and string. #include using namespace std; struct node { int data; struct Node *next; }; struct Node* head = nullptr;//or Null or 0; void insert(int new_data) { struct Node* new_node=(struct Node*) new(struct Node); new_mode->data=new_data; new_mode->next=head; head=new_node; } void display() { struct Node* ptr; ptr=head; while(ptr ! = NULL) {   cout<data<<""; ptr=ptr->next; } } int main() { insert{2}; display{}; return0;

Data structures remove_char(str_list:list, char:str) -> list This function will be given a list of strings and a character. You must remove all occurrences of the character from each string in the list. The function should return the list of strings with the character removed.  Example: str_list = ['adndj', 'adjdlaa', 'aa', 'djoe'] char: a output = ['dndj', 'djdl', '', 'djoe']

Question 9 #include using namespace std; struct ListNode { string data; ListNode *next; }; int main() { ListNode *ptr, *list; list = new ListNode; list->data = "New York"; ptr = new ListNode; ptr->data = "Boston"; list->next = ptr; ptr->next = new ListNode; ptr->next->data = "Houston"; ptr->next->next = nullptr; // new code goes here Which of the following code correctly deletes the last node of the list when added at point of insertion indicated above? O delete ptr->next; ptr->next = nullptr;; O ptr = list; while (ptr != nullptr) ptr = ptr->next; delete ptr; O ptr = last; delete ptr; list->next->next = nullptr; delete ptr; O None of these
