Chapter 2, Problem 14SA
Explanation of Solution
Let us number the statements as follows:
(1) x = 7; y = 2 * x - 3;
(2) z = x + y - 3;
(3) x = z / y;
(4) y = z - x;
(5) w = x + y + 2 * z;
(6) w–;
(7) y = 2 * w + z - x;
The execution is explained in the table below. '?' indicates that the value is unknown.
