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,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;
}
