How to change the fundamental underlying container type for the adaptor containers?


How to change the fundamental underlying container type for the adaptor containers?

will help you I want to use stack, which uses list as a fundamental container and not vector. How can I do so? As I know by default the stack will use vector. How can I ensure that the stack will use only the container I have mentioned. For example, I want stack to use - list only. , Give the required container as templatized parameter. For example:
code :
std::stack<int,std::vector<int> > stack_using_vector_of_int;
std::stack<std::string,std::list<std::string> > stack_using_list_of_string;
template <typename T>
using list_stack = std::stack<T, std::list<T>>;

Is there a priority_queue adaptor for boost pointer containers?

it helps some times A priority queue is not really a new container. You should be able to "create" it based on a ptr_vector using a typedef:
code :
typedef priority_queue<myclass, ptr_vector<myclass> > ptr_priority_queue;

wish helps you The underlying container for a priority_queue must be a sequence container with random access iterators (and front(), push_back() and pop_back() operations). list has bidirectional iterators, not random access iterators, so you can't use it here.
You can use vector (the default), deque, or any non-standard container that meets these requirements.

With these it helps I found a possible explanation here: Implementation of alignof
code :
  struct Double { double d; };
  __alignof__ (double) == 8
  __alignof__ (Double) == 4;
  __alignof__ (double) == 8
  __alignof__ (long double) == 4;

wish help you to fix your issue You have part of the solution already: using [] on the generic parameter.
The part you are missing: you need to use Unchecked.equals instead of the normal = operator within your map implementation (anywhere you're checking the equality of two 'a values). Unchecked.equals checks at run-time whether the type supports generic equality. If it does, it compares the two instances/values for equality as usual; if not, it falls back to a structural equality check or the type's implementation of the Object.Equals(obj) method.

this one helps. I want to be able to create a function where I specify a parameter to have both a templated container and a templated element type for that container. Is this possible? I get "error C2988: unrecongnizable template declaration/definition" among others. Here is the function in question. , You would need to use a template template parameter, e.g.,
