Joe would most likely use a variable to store a number that changes over the duration of the program's run.
A variable is a container that stores a value that can be changed during the execution of a program. It is a named storage location in computer memory that is used to hold data while the program is running. Variables are used to store data that needs to be manipulated, processed, or used in a program.
A loop is a programming structure that repeats a set of instructions until a specified condition is met. It is typically used when a set of instructions needs to be repeated multiple times in a program.
A constant is a fixed value that cannot be changed during the execution of a program. It is typically used when a value needs to remain constant throughout the program's run, such as the value of pi or the number of days in a week.
A function is a block of code that performs a specific task and can be called by other parts of a program. Functions can be used to group related instructions together and make them easier to reuse in other parts of a program.
In summary, a variable is the most appropriate choice for storing a number that changes over the duration of the program's run, as it allows the value to be manipulated and updated as needed during the program's execution.
