You can have more than one constructor. A constructor has no return type and no return statement. C++ gives every class a default (implicit) constructor that takes no arguments, and does nothing. A destructor is
A destructor is a method that is executed when an object is destroyed. Not all object-oriented programming languages support destructors, which are usually used to release system resources (for example, main memory allocated by the object). Java, in particular, does not use destructors because it...
Expression has the type '<typename>' which is a restricted type and cannot be used to access members inherited from 'Object' or 'ValueType' Expression is a value and therefore cannot be the target of an assignment Expression is not a method Expression is not an array or a method, and ca...
As you might have figured out, the answer to last week's puzzle is "if the constructors and initializers run in their actual order then an initialized readonly field of reference type is guaranteed to be non null in any possible call. That guarantee cannot be met if...

Thus changes to one will show up in two and vice-versa. This is dangerous, especially when the destructors for both one and two try to deallocate the memory for theString. In situations like these, you'll need to override C++'s default behavior by providing your own copy constructors and...
why destructors execute in reverse order in C++? Why do I get the errors below when I use the /ENTRY option for the linker in a C++ project? why do I have only one letter displayed in my window title, when there are a few words in the title string? Why doesn't DWORD allow conver...

A destructor/disposer conceptually turns an object back into raw memory. Therefore, just like all other nonprivate methods, destructors/disposers assume as a precondition that “this” object is actually a valid object and that its invariants hold. Hence,destructors/disposers only run on successfully...
