#SupportHeForShe Government can give you nothing but what it takes from somebody else. A government big enough to give you everything you want is big enough to take everything you've got, including your freedom.-Ezra Taft Benson You must accept 1 of 2 basic premises: Either we are alone in the universe or we are not alone. Either way, the implications are staggering!-Wernher von Braun
I presumed that was implied when i mentioned the namespace scope resolution operator (it's the same operator) :)

List the distinct uses for a colon in C++. Motivated by currently writing a function that had better take all of them into account! :-D

Nah, looks like C++11. e.g. for (auto it : vector) Range-based for loop (since C++11) - cppreference.com[^]

The fox knows many things, but the hedgehog knows one big thing.Hi. I would like to help with the answer to your question.

The two colons are the scoping operator.
Used to access the elements of the namespace. But in this matter, the editors of this site are more competent. Read more here: [url=https://sirinsoftware.com/services/iot-development/\]https://sirinsoftware.com/services/iot-development/\[/url\]
