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) static uint8_t buffer[sizeof(Block)];

int main() {
    int id, value;
    cin >> id >> value;
    Block *Ptr = new (buffer) Block;
    Ptr->id = id;
    Ptr->value = value;
    cout << Ptr->id << " " << Ptr->value ;
    // Write your placement new construction code here

    return 0;
}
