Что выведет следующий код на C#?


using System;

class Program {
static void Main() {
int a = 1000;
int b = 1000;

object x = a;
object y = b;

Console.WriteLine(x == y); // #1
Console.WriteLine(x.Equals(y)); // #2
}
}


🔢 Варианты ответа:

A)

True


B)

False


C)

True


D)

False


Правильный ответ: C

💡 Почему?

-
x и y — boxed значения типа int, то есть ссылки на два разных объекта в куче.
-
x == y сравнивает ссылки, а не значения → False.
-
x.Equals(y) вызывает метод Equals для int, который сравнивает значения → True.

📌 Подвох — в различии
== и .Equals() при использовании упакованных типов.

Telegram hopes to raise $1bn with a convertible bond private placement

The super secure UAE-based Telegram messenger service, developed by Russian-born software icon Pavel Durov, is looking to raise $1bn through a bond placement to a limited number of investors from Russia, Europe, Asia and the Middle East, the Kommersant daily reported citing unnamed sources on February 18, 2021.The issue reportedly comprises exchange bonds that could be converted into equity in the messaging service that is currently 100% owned by Durov and his brother Nikolai.Kommersant reports that the price of the conversion would be at a 10% discount to a potential IPO should it happen within five years.The minimum bond placement is said to be set at $50mn, but could be lowered to $10mn. Five-year bonds could carry an annual coupon of 7-8%.

The seemingly negative pandemic effects and resource/product shortages are encouraging and allowing organizations to innovate and change.The news of cash-rich organizations getting ready for the post-Covid growth economy is a sign of more than capital spending plans. Cash provides a cushion for risk-taking and a tool for growth.
