Chapter 2, Problem 7P

The “divide and average” method, an old-time method for approximating the square root of any positive number a can be formulated as

$x=\frac{x+a\text{/}x}{2}$

(a) Write well-structured pseudocode to implement this algorithm as depicted in Fig. P2.7. Use proper indentation so that the structure is clear.

(b) Develop, debug, and document a program to implement this equation in either a high-level language or a macro language of your choice. Structure your code according to Fig. P2.7.
