c++ - クラスの 2 つのオブジェクトを加算した結果を返す方法

Question

コンパイルすると、オブジェクトの追加結果を返すときにsme errordelete関数を使用するように見えます。constexpr Player::Player(const Player&)

#include <bits/stdc++.h>

using namespace std;

class Player
{
  char* name;
  int num;

 public:
  Player(char* str = nullptr, int n = -1)
      : name{str}
      , num{n}
  {
    if (str != nullptr)
    {
      name = new char[strlen(str) + 1];
      strcpy(name, str);
      str = nullptr;
    }
  }

  Player& operator=(const Player& temp)
  {
    delete[] this->name;
    this->name = new char[strlen(temp.name) + 1];
    strcpy(this->name, temp.name);
    this->num = temp.num;
  }

  Player operator+(const Player& temp);
};

Player Player::operator+(const Player& temp)

{
  char* str = new char[strlen(name) + strlen(temp.name) + 1];

  strcpy(str, name);
  strcat(str, temp.name);

  int n = num + temp.num;

  Player result{str, n};

  delete[] str;

  return result;
}

int main()

{
  Player p1{"abc", 11};
  Player p2{" xyz", 9};
  Player p3;

  p3 = p1 + p2;
}
