Placement New Static Buffer

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

struct Block{
    int id;
    int value;
};

// Define your struct and placement new logic here

int main() {
    int id, value;
    cin >> id >> value;
    alignas(Block) static unsigned char buffer[sizeof(Block)];
    Block* blockPtr = new (buffer) Block;
    blockPtr->id = id;
    blockPtr->value = value;
    cout<<blockPtr->id<<" "<<blockPtr->value;
    blockPtr->~Block();

    // Write your placement new construction code here

    return 0;
}
