1.	What is the use of the sqrt() function?(a) To find the square of a number(b) To find the square root of a number(c) To find the cube root of a number(d) To find the cube of a numberThe question was posed to me in an interview.Question is taken from Mathematical Functions in section Arduino Programming of Arduino
Answer» Right answer is (b) To find the SQUARE root of a number The best explanation: The sqrt() function is used to find the square root of a number. It takes ONE argument; the number whose square root is to be FOUND out. This function can accept any number-based datatypes and GIVES the output in the double datatype.
