Reinitialize Object In-Place

#include <iostream>
#include <cstdint>
#include <new>

using namespace std;

// Write your struct and placement new logic here
typedef struct Mode{
    int level;
};
int main() {
    int firstLevel, secondLevel;
    cin >> firstLevel >> secondLevel;

    // Write your in-place reinitialization logic here
    alignas(Mode) uint8_t buffer[sizeof(Mode)];

    Mode* p = new (buffer) Mode;
    p->level = firstLevel;
    p->~Mode();

    p = new (buffer) Mode;
    p->level =  secondLevel;
    cout << p->level;
    p->~Mode();

    
    return 0;
}
