Not giving the right value to a variable in the book 

At the end of bar(), it calls baz():

In the code baz is passed f  whose value is the address of d which is 9.

However, in the diagram, it is given a value of 4.

```
Address Name    Value
230     20
(230) - 1       5
... ... ...
12  g   100
11  f   4
10  e   9
9   d   (230) - 1
8   c   5
7   b   4
6   a   0
5   z   4
4   y   10
3   x   0
2   j   0
1   i   230
0   h   3
```
