Breaking code down

[Douggie Fox]

Hi,
If you have a long, tricky piece of code that needs decifering in the exam, does anyone have any techniques for keeping track of variables?

For tracing variables in loops, I use a table to keep track of iterations and values:
<pre>
int x=0;
int y=0;
for (int i = 0; i < 10; i++)
{
... do something with x and y
}

i : x : y
0 : ? : ?
1 : ? : ?
2 : ? : ?
3 : ? : ?
4 : ? : ?
</pre>
Use a similar technique for tracing through various methods.
