in C++. Write a function squareRoot that uses the Newton’s method of approximate calcu-lation of the square root of a number x. The Newton’s method guesses the square root in iterations. The first guess is x/2. In each iteration the guess is improved using ((guess + x/guess) / 2 ) as the next guess. Your main program should prompt the user for the value to find the square root of (x) and how close the final guess should be to...
