C++ Standard update

Overview: C++ Gets an Overhaul

As I’m new, most of that is right over my head. What I do get out of it is they’re going to be adopting a lot of the Boost libraries. Little surprise there as I read a lot about the Boost libraries.

Here is one part that show how new I am to C++:

C++0x also removes some embarrassments from the language. For example, C++03 has at least three different forms of initialization:

1
2
3

int x=0;
int x(0);
int y[2]={1,2};

C++0x defines a unified initialization notation which can even be used in the declaration of dynamically allocated arrays:

1
2
3
4
5
6
7
8

int* a = new int[4] {1, 10, 20,95 };
vector<string> vs={"ab","cd","ef"};
 
class S {
 int arr[3];
public:
  S() : arr{ 1, 2, 3 } {}
};

I knew about the syntax for the first two in the list but had not seen the third or had seen it described differently. The last code block looks a little alien to me. Perhaps that’s just because my exposure to C++ classes is so limited.

Either way, this is definitely a month for change in the C++ world:

The vast number of new features forces the committee to work at an incredible speed. A clear statement of intent was made to complete work on the new standard at the San Francisco meeting of September 2008 in order to achieve publication in 2009.
