A programmer needs to perform the same complex calculation on different data at various points within an application. To avoid rewriting the same block of code multiple times, which programming concept should the programmer use?
Function
Constant
Loop
Variable
The correct answer is a function. A function is a reusable, named block of code that performs a specific task and can be called multiple times from different parts of a program. A variable is a named storage location for a value that can change, but it does not contain a block of executable code. A loop repeatedly executes a block of code in a single location as long as a condition is met, but it does not create a reusable, callable unit for the entire program. A constant is an identifier whose value cannot be changed during program execution.
