What is ... (I mean the ... symbol)?

Question

Sooooo, in one of the codes in SL that involved switch statements, i saw that to check if the value is in the range of two numbers, the user wrote: ... . What exactly is this symbol and can I use it outside a switch statement?

Answer 1

From the looks of it (after some googling haha), those types of ellipsis seem to be known as case ranges, and can only be uses when defining a specific range of number in a switch statement -

Answer 3

What exactly is the code that you're referring to? To my knowledge, the only use of ellipsis (...) in C++ is for passing unknown parameters to a function 🤷‍♂️
