What's strong code? Writing sturdy code is known as a query approximately what the code is attempting to unravel. (And solid code isn't to be harassed with styles simply because no longer all items of excellent code are styles. ) We debate approximately solid code simply because there's not only a unmarried piece of fine code, yet such a lot of strong items of code.

It depends. If MyType is a value type, you've made one allocation. The size of that allocation is twice the size of MyType. However, if MyType is a reference type, you've made three allocations: one for the C object, which is 8 bytes (assuming 32-bit pointers), and two more for each of the MyType objects that are contained in a C object. The difference results because value types are stored inline in an object, whereas reference types are not. Each variable of a reference type holds a reference, and the storage requires extra allocation.
Even calls to virtual functions are sent to the base class version. The Java language responded by more or less removing value types from the language. All user-defined types are reference types. In the Javalanguage, all parameters and return values are passed by reference. This strategy has the advantage of being consistent, but it's a drain on performance. Let's face it, some types are not polymorphicthey were not intended to be. Java programmers pay a heap allocation and an eventual garbage collection for every variable.
Equals (right); } This example code introduces both of the methods I have not discussed yet: operator==() and the instance Equals() method. I'll explain both in detail, but I'm not ready to end my discussion of the static Equals() just yet. For right now, I want you to understand that static Equals() uses the instance Equals() method of the left argument to determine whether two objects are equal. Equals() method because it already does exactly what it needs to do: determines whether two objects are the same when you don't know the runtime type.
