goto the head of the class!
If you can't laugh at yourself - ask me and I will do it for you.

Just to be on the safe side, be sure to consider this is the most distinct use of the colon.[^]

I presumed that was implied when i mentioned the namespace scope resolution operator (it's the same operator) :)

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. First, one colon is used to indicate the base class when inheriting from classes. Second, a single colon is used to specify the initialization list for the constructor. 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/\[/url\]
