What term is used in programming to describe a value that does not change after it has been initially set?
Variable
Constant
Identifier
Function
In programming, a constant is a value that is defined once and does not change throughout the execution of code. It is important because it provides a way to label data with a descriptive name and prevent accidental changes that can lead to errors. Unlike variables, which can be modified, constants remain unchanged, which is useful for representing fixed values such as mathematical constants (pi, e), configuration values (screen resolution, colors), or any other constant data within a program.
