What is the difference between declarative and imperative programming? [closed]
...imperative programming is LINQ.
With imperative programming, you tell the compiler what you want to happen, step by step.
For example, let's start with this collection, and choose the odd numbers:
List<int> collection = new List<int> { 1, 2, 3, 4, 5 };
With imperative programming, w...
What's the best name for a non-mutating “add” method on an immutable collection?
Sorry for the waffly title - if I could come up with a concise title, I wouldn't have to ask the question.

What is the curiously recurring template pattern (CRTP)?
... Apple a2;
a1.size = 10;
a2.size = 10;
if(a1 == a2) //the compiler won't complain!
{
}
}
This could seem that you would write less if you just wrote operator == for Apple, but imagine that the Equality template would provide not only == but >, >=, <= etc. And you...
How can I reliably get an object's address when operator& is overloaded?
...d of boost::addressof.
Let us first copy the code from Boost, minus the compiler work around bits:
template<class T>
struct addr_impl_ref
{
T & v_;
inline addr_impl_ref( T & v ): v_( v ) {}
inline operator T& () const { return v_; }
private:

Why is there a difference in checking null against a value in VB.NET and C#?
...de different assumptions about usage; in this case the semantics of a NULL comparison.
My personal preference is for the VB.NET semantics, which in essence gives NULL the semantics "I don't know yet". Then the comparison of 5 to "I don't know yet". is naturally "I don't know yet"; ie NULL. This has...
techniques for obscuring sensitive strings in C++
...OR key2
If you create key1 with the same byte-length as key you can use (completely) random byte values and then compute key2:
key1[n] = crypto_grade_random_number(0..255)
key2[n] = key[n] XOR key1[n]
You can do this in your build environment, and then only store key1and key2 in your applicatio...
