When to use Preorder, Postorder, and Inorder Binary Search Tree Traversal strategies
...a replica of a tree, put the nodes in an array with a pre-order traversal. Then perform an Insert operation on a new tree for each value in the array. You will end up with a copy of your original tree.
In-order: : Used to get the values of the nodes in non-decreasing order in a BST.
Post-order: : ...
What is the difference between quiet NaN and signaling NaN?
...bugging. For example, floating-point objects might be initialized to sNaN. Then, if the program fails to one of them a value before using it, an exception will occur when the program uses the sNaN in an arithmetic operation. A program will not produce an sNaN inadvertently; no normal operations prod...

...ssue, depending on the context. If used for a giant table of 1000 results then it will be more important but if only used for a single value, the difference is negligible. But the advantage is that it's locale-aware, so someone in Europe would see 34.523.453,345 or 34 523 453,345. This would be m...
Why can templates only be implemented in the header file?
...on solution to this is to write the template declaration in a header file, then implement the class in an implementation file (for example .tpp), and include this implementation file at the end of the header.
Foo.h
template <typename T>
struct Foo
{
void doSomething(T param);
};
