Is the order of iterating through std::map known (and guaranteed by the standard)?
...
This is guaranteed by Associative container requirements in the C++ standard. E.g. see 23.2.4/10 in C++11:

non-descending is defined by t...

Delegates can be used to define callback methods.
Delegates can be chained together; for example, multiple methods can be called o...
Why should we typedef a struct so often in C?

they're pretty harmless. However, when

...
With C++17, shared_ptr can be used to manage a dynamically allocated array. The shared_ptr template argument in this case must be T[N] or T[]. So you may write
shared_ptr<int[]> sp(new int[10]);
