Reinitialize Object In-Place

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

using namespace std;

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

    // Write your in-place reinitialization logic here
    alignas(Mode) uint8_t buf[sizeof(Mode)];
    Mode* p=new (buf) Mode{firstLevel};
    p->~Mode();
    p=new (buf) Mode{secondLevel};
    cout<<p->level;
    p->~Mode();
    return 0;
}
