How to declare std::unique_ptr and what is the use of it?
...rm for creating a unique pointer is better, when possible. Notice, that in C++14 we will be able to do:
unique_ptr<int> p = make_unique<int>(42);
Which is both clearer and safer. Now concerning this doubt of yours:
What is also not clear to me, is how pointers, declared in this wa...
Design by contract using assertions or exceptions? [closed]
... if you leave them enabled - at least in Eiffel. I think to do the same in C++ you need to type it yourself.

...astException that prevent further damages if you lied (other language like C++ won't check at run-time - you have to know what you do)
Finally, if you really need, you might rely of run-time type identification (i.e.: instanceof) to check the "real" type of an object before attempting to cast it. B...

How to use a class from one C# project with another C# project
...and add to the current solution. This problem occurs for Python, java, c#, C++ and C project folders.
The new developer selecting "new>project>project name and changing the solution directory to "use same solution" still creates a new "project" in the same solution space, but not in the same ...
Why do std::shared_ptr work
...
This behavior is guaranteed by the C++ standard, right? I need type erasure in one of my classes, and std::shared_ptr<void> lets me avoid declaring a useless wrapper class just so that I could inherit it from a certain base class.

Any difference between First Class Function and High Order Function
...unctions as such. But something similar is the case e.g. with templates in C++: templates are higher-order (you can have "template template parameters"), but not first class values, i.e., templates cannot be parameters to ordinary functions. Similarly with e.g. modules/functors in ML.
