Does C++ support 'finally' blocks? (And what's this 'RAII' I keep hearing about?)

Question

Does C++ support \'finally\' blocks?

What is the RAII idiom?

What is the difference between C++\'s RAII idiom and C#\'s \'using\' statement?

Answer 1

As many people have stated, the solution is to use C++11 features to avoid finally blocks. One of the features is unique_ptr.

Here is Mephane's answer written using RAII patterns.

#include 
#include 
#include 
using namespace std;

class Foo
{
 ...
};

void DoStuff(vector input)
{
    list > myList;

    for (int i = 0; i < input.size(); ++i)
    {
      myList.push_back(unique_ptr(new Foo(input[i])));
    }

    DoSomeStuff(myList);
}
