I'm struggling to understand what the auto keyword is for and
it's appropriate uses. From research, it seems to share the
same capabilities as the var keyword in C#. From the C#
documentation, it states:
https://docs.microsoft.com/en-us/dotnet/csharp/language-reference/keywords/var
... variables that are declared at method scope can have an
implicit "type" var. An implicitly typed local variable is
strongly typed just as if you had declared the type yourself,
but the compiler determines the type.
Is the same true for auto? For example, if I have a class
Person, I might have attributes such as FirstName, LastName
which should obviously be strings but will D allow me to
declare class level attributes with auto?
C# doesn't allow this.
It basically works like C#.
auto x = "hi";
will make x a string.
But if you later try:
x = 5;
it will throw an error, because x is a string. It's used to save
you the typing of the type, it doesn't make the language
dynamically typed.
