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;
    alignas(Block) uint8_t buffer[sizeof(Block)];
    Block* ptr = new (buffer) Block;
        ptr->id = id;
    ptr->value = value;
    cout << ptr->id << " " << ptr->value;
    // Write your placement new construction code here
    ptr->~Block();
    return 0;
}
