Suppose I have this function:
void my_test()
{
A a1 = A_factory_func();
A a2(A_factory_func());
double b1 = 0.5;
double b2(0.5);
A c1;
A c2 = A();
A c3(A());
}
In each grouping, are these statements identical? Or is there an extra (possible optimizable) copy in some of the initializations?

I'm writing a simple ini file parser and I'm having a little problem with the initialization of the object in the "do" clause. It wants me to return a unit but i can't get the blankity function to do the side effects if I try to pipe into an "ignore" or if i return "()" directly.
This code works as a separate function because I can igno...
I'm currently looking at a function example that I can't seem to figure out using MFC in Visual C++. The function is as follows
CMFC_OSG_MDIView::CMFC_OSG_MDIView() :mOSG(0L)
{
}
I understand everything here except the mOSG(0L) snippet. mOSG was declared in the MFC_OSG _MDIView class as follows:
cOSG* mOSG;
Any help is greatly appr...
I want to have a static array with arrays in it. I know you can make a normal array like this:
int test[] = {1,2,3,4};
But I want to do something like this (Xcode gives me a bunch of warnings and stuff):
int test[] = {{1,2}, {3,4}};
In python it would be:
arr = [[1,2], [3,4]];
What's the proper way to do this?

I create a new object of type Spam, with attr_accessor to both hooray and name and I have the initialize method. I'm expecting when I create a new object the object is loaded with a var of name with "Whammy" and a empty array named hooray. Though I'm not getting this behavior. Can anyone explain, thank you in advance.

I have a static library with the following code:
h file:
class Foo
{
public:
Foo()
{
a = 4;
}
int a;
};
class Bar
{
public:
static const Foo foo;
};
cpp file:
const Bar::foo = Foo();
My problem is that Bar::foo does not get initialized with a=4 until some time after main(). Before then a=0. I'm trying to ...
