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;
};

alignas(Block) std::byte buffer[sizeof(Block)];

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

    // Write your placement new construction code here
    Block* wskBlock = new (buffer) Block();

    wskBlock->id = id;
    wskBlock->value = value;

    cout << wskBlock->id << " " << wskBlock->value;

    wskBlock->~Block();

    return 0;
}
