Which type of parameters are used for providing output from a function?

In the context of functions, output parameters are specifically designed to convey data from the function back to the caller. When a function is executed, it may perform operations or calculations that result in data that needs to be returned. Output parameters serve this purpose by allowing the function to provide results without being limited to just returning a single value.

This is particularly useful in scenarios where multiple values need to be passed back or when you want to maintain clarity in your function's return type. By utilizing output parameters, you can define a function signature that explicitly indicates what outputs will be produced, aiding in the understanding and usability of the function by other developers.

Other types of parameters, such as input parameters, are used to pass data into a function, while local parameters are used internally within the function for its computations. Reference parameters allow modifications to be made to the passed arguments but do not specifically imply an output mechanism on their own. Hence, the correct choice for conveying output from a function is indeed output parameters.
