Question: Use weak_ptr for shared_ptr like pointers that can dangle.
int main{
shared_ptr name2(new Name2(“Donald Duck”));
delete name2;
weak_ptr name3= move(name2);
return 0;
}
does this work for the question? Can you also give me another example if I'm wrong
Using C++ Visual Studio
the code provided is possible in c++ as name2 is a value or string but we are directly using the name2 and moving it into name3 which is part of pointer weak_ptr .

1.Please explain in detail Scott Meyers’s point: Use weak_ptr for shared_ptr like pointers that can dangle. Hint: a correct explanation should also discuss dangling raw pointer. 2. In your understanding, why weak_ptr was not named strong_ptr? Please explain in detail how weak_ptr’s functions expired() and lock() work.
The question I want answered is in C++. How can I pass a value to a function and create a new linked list out of it? For example I have: void getIntegerInput(List<int> list) { int s; std::cout << "Type a positive integer then click enter to add it to the linked list\n"; std::cout << "Type -1 to stop\nType -2 to delete an item from the list\n"; std::cin >> s; while (s != -1) { if (s == -2) { int...
PLEASE USE C++ Source Code
Attached is a linked list with 2 nodes. You can use this or
write a similar one. The assignment is to write 2 functions. One
function will add another node at the end of the list. The other
function will delete a node. Don't forget - No dangling pointers
!
Example linked source code attached below
#include<iostream>
using namespace std;
class Node
{
int data;
Node *next;
public:
void setdata(int d) {data = d;}

I'm trying to write a program in C that calculates the area of a rectangle. I need to have a function that gets dimensions from a user and stores them with pointers and addresses and another function that calculates the area... my question is how do i access that values from the dimension function so that I can use it in my calculation and main function.. for example. void userDimensions(float *base, float *height){ scanf("%lf" , base); scanf("%lf", height); } float...

Make sure its corect and runs without errors and I promise to
give you a thumbs up.

Introduction: One of the most important uses of pointers is for dynamic allocation of memory. In C++ there are commands that let the user request a chunk of memory from the operating system, and use this memory to store data. There are also commands to return memory back to the O/S when the program is finished using the data. In this lab, we will explore some of the things that can go wrong when using dynamic memory and discuss how...
