also static in C#
as in:
static string tempVar;

static is a C# keyword,
Its Shared in VB

The classic VB "static" keyword and the C# static (and VB.NET "Shared")
modifiers are not the same thing. In classic VB, "static" was used to retain
the value of a variable inside a function.
Shared and Static in VB.NET and C# respectively mean, when applied to a
variable, that all instances of the object share the same piece of data.

Like C ?
What about simply moving it outside the function (and make
it static if it is a static method) ?
Arne
You could certainly do that. But my point to the OP was, if you are comparing
against classic VB there is no direct equivalent: http://msdn2.microsoft.com/en-us/library/z2cty7t8.aspx

The "static" local variable in VB is not limited to "classic" VB, but is
alive and well in VB.NET also.
There is no C# equivalent. It can be replaced by a class-level instance or
static variable in C# (depending on whether the original method was an
instance or static method), but this doesn't quite capture the usefulness of
the local static variable.

It does, however, *exactly* capture the semantics - as that's what the
VB.NET compiler converts the code into.
Personally I'm glad that C# doesn't have statics. Persistent state
should be a property of types and objects, not methods. Whenever a
method feels like it needs state, consider whether that state is
inherently part of the object, or whether it should be part of a new
class in its own right, which the object has a reference to an instance
of.

No if. C/C++ local statics are reused between all invocations, independent
of arguments (the this pointer is really an argument). So you can use a
global variable or a class static to get the same result.

Giudo has suggested adding optional static typing to Python.
(I hope suggested is the correct word.)
http://www.artima.com/weblogs/viewpost.jsp?thread=85551
An example of the syntax he proposes is:
> def f(this:that=other):
> print this
This means that f() has a 'this' parameter, of type 'that'.
And 'other' is the default value.

Hello fellow C programmers,
I'm just learning to program with C, and I'm wondering what the
difference between signed and unsigned char is. To me there seems to
be no difference, and the standard doesn't even care what a normal char
is (because signed and unsigned have equal behavior).
For example if someone does this:
unsigned char a = -2; /* or = 254 */
