1.	What is the use of the sq() function?(a) To find the square root of a number(b) To find the square of a number(c) To find the cube of a number(d) To find the cube root of a numberThe question was posed to me in unit test.This interesting question is from Mathematical Functions topic in portion Arduino Programming of Arduino
Answer» CORRECT answer is (b) To find the square of a number For EXPLANATION I WOULD SAY: The sq() function is used to find the square of a number. It takes ONE argument; the number whose square is to be found out. This function can accept any number-based datatypes and gives the output in the double datatype.
