std::shared_ptr Basics and Reference Counting

Medium Smart Pointers

Solve in Playground →

Problem Statement

Write a C++ program using `std::shared_ptr` to manage shared ownership and query reference counts via `use_count()`.

Input Format

A single integer N.

Output Format

Print reference count when multiple shared pointers reference the resource.

Constraints

-100000 <= N <= 100000

Sample Input

Sample Output

Value: 55, Use Count: 2

Explanation

`std::shared_ptr` allows multiple pointers to share ownership of the same resource, tracking references dynamically.

Starter Code

#include <iostream>
#include <memory>

int main() {
    int n;
    if (std::cin >> n) {
        // Write your shared_ptr and use_count logic here
    }
    return 0;
}
