NOTE: in mathematics, the square root of a negative number is not real; in C++ therefore, passing such a value to the square root function is an error. Given a double variable named areaOfSquare write the necessary code to read in a value , the area of some square, into areaOfSquare and print out the length of the side of that square. HOWEVER: if any value read in is not valid input, just print the message “INVALID”.
