Hiçbir şey anlamadım ama yine de eğlenceli.

NOT CURRENT üzerinde yinelenen bir nesne oluştururken 4200 hatası atılmıyor (ki bu hala geçerli olanı veriyor - [günlükte "GEÇERLİ ŞEKİL"e bakın]),

ve aynı zamanda, GÜNCEL OLMAYAN bir çizelgede bir nesneyi aramanın, mevcut bir çizelgede arama yapmaktan 500 kat daha fazla zaman aldığı tespit edildi.

a :), çünkü buna sahip olan tek kişi ben değilim.

 
fxsaber :
Bu tür dizilerin akıllıca başlatılamayacağını doğru anlıyor muyum?

Ve yalnızca işlevlere/yöntemlere giriş parametreleri olarak anlamlı mı?

 class A {
public :
         void f() {}
};
A* const a[ 10 ] = { NULL };
void OnStart ()
{
        A *aa = new A;
         ((A *)a[ 9 ]) = aa; //нет ошибки при компиляции
               a[ 9 ].f();   //нет ошибки при выполнении
         Print ( a[ 9 ] == aa ); //Результат: false
}

Bunun mümkün olduğunu düşünebilirsiniz, ancak örnekten de görebileceğiniz gibi, ince hatalara yol açar.

 
A100 :
((A *)a[ 9 ]) = aa; //нет ошибки при компиляции

Evet, burada bir derleyici hatası var, ancak yürütme bu noktanın ötesine geçmiyor - geçersiz işaretçi .

Yani, aslında, başlatma imkansızdır.

O zaman hata aynı zamanda 32-bit sürümler için (sadece buna sahibim) hatasız yürütmedir. geçersiz işaretçi - yalnızca sınıfa bir üye eklerseniz, örneğin int i
