Easy Dynamic Memory & Smart Pointers

Problem Statement

Include the “ header. In `main()`, read an integer, and allocate it using `std::make_unique(val)`. Dereference the smart pointer to print ‘Smart: [val]’.

Input Format

A single integer.

Output Format

Print the dereferenced value.

Constraints

C++14 or higher (std::make_unique).

Sample Input

Sample Output

Smart: 2026

Explanation

Modern C++ heavily discourages raw `new` and `delete`. The `` header provides smart pointers that automatically handle deallocation.

Starter Code

#include <iostream>
// Include memory header here

int main() {
    int val;
    if (std::cin >> val) {
        // Create unique pointer and print
    }
    return 0;
}
