class Counter
{
public int Number { get; set; }
// qo'shish operatorini aniqlash
}
Bu sinfda int tipidagi int tipidagi ob'yekt bilan Counter ob'yektini qo'shish operatori aniqlangan:
Counter counter = new Counter { Number = 45 };
int x = counter + 6;
Console.WriteLine(x);
Counter sinfida aynan qaysi operator aniqlanganini toping
Javoblardan birini tanlang:
1) public static Counter operator + (int val, Counter counter)
{
return new Counter {Number = counter.Number + val};
}
2) public int operator + (Counter counter, int val)
{
return counter.Number + val;
}
3) public static Counter operator + (Counter counter, int val)
{
return new Counter {Number = counter.Number + val};
}
4) public static int operator + (Counter counter, int val)
{
return counter.Number + val;
}
