in a clean simple manner?
Basically, I want a path that will be host.com/:parent\_id/:parent\_id/:id with N numbers of :parent\_id. Pretty much how Wordpress-articles are routed.
I don't believe route globbers is the solution, but I might be wrong. It seems to give the same result for host.com/:id and host.com/foo/ba... | [

if the route globbers solution would take care of generating the URLs with parent IDs though.

You don't need the parent IDs to perform the routing, correct? You just want to include them in the URLs and route those requests the same as if using the URLs like `example.com/chapter1`, correct?

Either way, you'll need to generate URLs that include the parent IDs, so duplicate content issues probably aren't too likely if you only link to those resources using those URLs. | [

when you cast `a` from its original type to `int *`, you're telling the compiler to forget about its original declaration, effectively losing its 2-dimensionality and becoming a simple vector of `int`s.
Here's how to understand the declaration of `p`:

p[0] = { 1, 2, 3 }
p[1] = { 2, 3 }
p[2] = { 3 }

```
Note that you can use the function `ceil` to accomplish the same result:
```
int a = 22;
int b = ceil((float)a / 5) * 5; // b = 25;
```

**Old Answer:**
To round to the nearest multiple of `5`, you can do the following:
```
int a = 23;
int b = (int)(a + 2.5) / 5 * 5;

I found out that `template <class T> std::size_t hash_value(T* const& v)` in `boost/functional/hash.hpp` on line #215 (Boost 1.49) is Boost's specialization for pointers and it simply masks your custom implementation of `hash_value` suc... | [

Both of these can be defined generically by using a templated `operator()` in a non-templated class.
