When should I use smart pointers in C++?

Smart pointers in C++ should be used when you want to manage dynamic memory automatically, preventing memory leaks.

What are the different types of smart pointers?

The main types of smart pointers in C++ are std::unique_ptr, std::shared_ptr, and std::weak_ptr, each serving different purposes.

Can you give me an example of using std::shared_ptr?

Sure! Here's a simple example:

#include <iostream>
#include <memory>

void example() {
    std::shared_ptr<int> ptr1 = std::make_shared<int>(10);
    std::shared_ptr<int> ptr2 = ptr1;
    std::cout << *ptr1 << " " << *ptr2 << std::endl;
}

What are the advantages of using smart pointers over raw pointers?

Smart pointers help manage memory automatically, reduce the risk of memory leaks, and provide better exception safety.
