Placement New Static Buffer

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

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

alignas(Block) uint8_t buffer[sizeof(Block)];




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

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

    s->id = id;
    s->value = value;
    
    cout << s->id << " " << s->value;

    s->~Block();

    return 0;
}
