How do you save a value to a variable?

To save a value to a variable, the key method is by using the assignment operator. This operator, often represented by the equals sign (=), allows you to assign a value or expression to a variable name. For example, in the expression x = 5, the value 5 is stored in the variable x. This fundamental concept is essential in programming, as it enables the storage and manipulation of data throughout the code.

Other methods mentioned, such as defining a function, creating a loop, or declaring an array, relate to various programming tasks, but they do not directly involve the process of saving or assigning values to individual variables. Functions encapsulate blocks of code for reuse, loops execute a set of instructions multiple times, and arrays are data structures that hold multiple values under a single name but do not intrinsically assign values to single variables.
