👉 Undercircled is a term used in computer programming to denote an identifier that represents a variable or constant. It is often used in C and C++ for variables, functions, classes, etc., which are designed to be used as part of a larger program. The "undercircled" notation is used because it helps to distinguish between the two types of identifiers: the one before the closing parenthesis ("") and the one after it (the identifier itself).
