Placement New Static Buffer

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

struct Block {
    int id;
    int value;
};

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

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

    Block* pointer = new (buffer) Block;

    pointer->id = id;
    pointer->value = value;

    cout << pointer->id << ' ' << pointer->value;

    pointer->~Block();

    return 0;
}
