Naming convention - underscore in C++ and C# variables
... It is safe and legal in functions, function prototypes, classes, structs, unions, enums and everything you put in a namespace. If you follow the common practice of putting all your code in namespaces then you are completely safe.

How do I keep track of pip-installed packages in an Anaconda (Conda) environment?
...e egg information. So you have basically three options.
You can take the union of the conda list and pip freeze and manage packages that were installed using conda (that show in the conda list) with the conda package manager and the ones that are installed with pip (that show in pip freeze but not...
Python Sets vs Lists
...from a sequence, and compute mathematical operations such as intersection, union, difference, and symmetric difference.
Usage
From some of the answers, it is clear that a list is quite faster than a set when iterating over the values. On the other hand, a set is faster than a list when checking if...
Why isn't sizeof for a struct equal to the sum of sizeof of each member?
... there is some order-guarantee in C++: "Nonstatic data members of a (non-union) class declared without an intervening access-specifier are allocated so that later members have higher addresses within a class object"

Constructor overload in TypeScript
...
I know this is an old question, but new in 1.4 is union types; use these for all function overloads (including constructors). Example:
class foo {
private _name: any;
constructor(name: string | number) {
this._name = name;
}
}
var f1 = new foo("bar");

Why does this C++ snippet compile (non-void function does not return a value) [duplicate]
...e possible types and the caller might need to cast it or extract it from a union.
So the deepest cause is probably the C language creators' belief that procedures that do not return any value are just an unimportant special case of functions that do; this problem got aggravated by the lack of focus...
Can enums be subclassed to add new elements?
... no.
As an example of a real problem take weekdays, weekend days and, the union, days of week. We could define all days within days-of-week but then we would not be able to represent properties special to either weekdays and weekend-days.
What we could do, is have three enum types with a mapping b...
What is the correct way to represent null XML elements?
...le would be elements of type decimal. If you want them to be empty you can union an enumerated string that only allows "" and a decimal, or use a decimal that is nillable.

Unnamed/anonymous namespaces vs. static functions
...ve.
Static only applies to names of objects, functions, and anonymous unions, not to type declarations.
Edit:
The decision to deprecate this use of the static keyword (affect visibility of a variable declaration in a translation unit) has been reversed (ref). In this case using a static or a...
