Which term is used to describe a value that may change during the execution of a program?

The term that describes a value that may change during the execution of a program is "Variable." In programming, a variable serves as a storage location identified by a name that can hold data. This data can be modified or updated as the program runs, allowing the program to process dynamic information. Variables are essential in making programs flexible and responsive to user input or changing conditions.

In contrast, a fixed value refers to data that does not change, while a constant is a specific type of fixed value that is defined once and does not change throughout the program. A literal represents a fixed value specified directly in the code, such as a number or string. Hence, the distinguishing characteristic of a variable is its ability to hold values that can be altered during the program's execution, making it a fundamental concept in programming.
