Question

What is the maximum number of arguments does the find() function accept?

(a) 1

(b) 2

(c) 3

(d) 4

The question was posed to me at a job interview.

My doubt is from Serial and Stream Communications topic in division Arduino Programming of Arduino

Answer 1

Correct answer is (b) 2

For explanation I would say: The find() function accepts a maximum of 2 parameters; the target which can be a set of characters, and the length of the target which denotes the lexical length of the target. This function then searches for the target throughout the stream and returns a Boolean True if a match is found, otherwise a Boolean False if the target is not found.
