Homonym: variable (Changeable)
A variable is a symbol or name that represents a value in programming, mathematics, or statistics. It can hold different values at different times, making it a fundamental concept for storing and manipulating data. For example, in a simple equation like x + 2 = 5, x is a variable that can change to solve the equation.
In programming, variables allow developers to create flexible and dynamic code. They can be used to store information such as user input, calculations, or even objects. For instance, a variable named score might keep track of a player's points in a game, changing as the player progresses.
