Understanding “Constants” in Programming — The Concept of an Unchanging Signpost | Funifytools

A constant is a fixed value in programming that never changes once defined.

Unlike variables, constants act like signposts labeled “Do Not Change.”

They make code clearer, more meaningful, and prevent accidental errors.

Common examples include values like PI = 3.14159 or MAX_SCORE = 100.

Use uppercase names and meaningful labels to identify constants easily.
