Which of the following statements about functional$-$style programming is false?

It lets you simply say what you want to do$.$ It hides many details of how to perform each task.

Typically, library code handles the how for you. This can eliminate many errors.

Functional$-$style programming emphasizes mutability$-$it uses only operations that modify variables' values.

Consider the for statement in many other programming languages.

Typically, you must specify all the details of counter$-$controlled iteration: a control variable, its initial value, how to increment it and a loop$-$continuation condition that uses the control variable to determine whether to continue iterating. This style of iteration is known as external iteration and is error$-$prone.
