Dynamic Object Allocation (new and delete)

Easy Dynamic Memory & Smart Pointers

Solve in Playground →

Problem Statement

Create a `Box` class with a public integer `value`. In `main()`, dynamically allocate a `Box` object on the heap using the `new` keyword, read an integer to set its `value`, print it, and then properly free the memory using `delete`.

Input Format

A single integer.

Output Format

Print 'Value: [val]'.

Constraints

Must use new and delete.

Sample Input

Sample Output

Value: 42

Explanation

Dynamic allocation allows objects to be created at runtime on the heap, but manual memory management via `delete` is required to prevent leaks.

Starter Code

#include <iostream>

class Box {
public:
    int value;
};

int main() {
    // Dynamically allocate Box, set value, print, and delete
    return 0;
}
