Placement New Static Buffer

#include <iostream>
#include <cstdint>
#include <new>
using namespace std;

// Define your struct and placement new logic here
struct Block {
    int id; 
    int value; 
};

int main() {
    int id, value;
    cin >> id >> value;

    // Write your placement new construction code here
    alignas(Block) uint8_t buffer[sizeof(Block)];
    Block *ptr = new (buffer) Block; 
    ptr->id = id; 
    ptr->value = value; 
    cout << ptr->id << " " << ptr->value;
    ptr->~Block(); 

    return 0;
}
