class Foo { public: template <typename F> void func(F f) private: int member_; };
file foo.cc
template <typename F> Foo::func(F f) { f(member_); }
file caller.cc...

Are you including foo.cc into caller.cc.

Is there a way that I can insert values into a VB.NET Dictionary when I create it? I can, but don't want to, do dict.Add(int, "string") for each item.
Basically, I want to do "How to insert values into C# Dictionary on instantiation?" with VB.NET.

It might look something like this:

If you need to do this frequently you could just inherit from the Dictionary class and implement it yourself .
I do not believe this is currently possible in VB.Net .

I hope I'm wording my question properly, but what I'm trying to do is actually rather trivial.
I have a bunch of code with static object instantiation that looks like this:
Foo *aFoo1 = [[[Foo alloc] init] autorelease]; [anArray addObject:aFoo1]; Foo ...

You'd probably want to use two files:
// Extra.h // new file with descriptive header NSArray* setupMyArray( .. .
My thought are to put the setup in a C function .

For quick tasks where I only use an instantiated object once, I am aware that I can do the following:
int FooBarResult = (new Foo()).Bar();
I say this is perfectly acceptable with non-disposable objects and more readable than the alternative:
Foo MyOnceUsedFoo...

The generated random numbers will be far from uniform.

Hi all,
I'm a C programmer trying to understand C++. Many tutorials demonstrate object instantiation using a snippet such as:
Dog* sparky = new Dog();
which implies that later on you'll do:
delete sparky;
which makes sense. Now, in the case when dynamic...

(For instance, libstdc++ contains the explicit instantiation of std::basic_string<char,char_traits<.

I am in need of some help here about doing a dynamic instantiation in C#. What I want to accomplish is to be able to use a string variable that is used as the name in the instantiation. I think you can use reflection or something, but I am lost on this...

If you already have a class called Averages,....

However I'm not entirely clear on what you're trying to do .
You can instantiate a class dynamically using Reflection, with Activator.CreateInstance .

Subsequent calls to the synchronized lazy-init factory method will be pretty much as fast as would calls to an unsynchronized eager-init method .
The overhead incurred by synchronized methods on a modern JVM is so small as to become insignificant .
