Variable Examination

If you pause the mouse over a variable name, it's current value is shown in a popup box. Try this on a few variables.
The variables window (accessible via the view menu) displays variables and their values from the the current expression (the auto tab), local to the current function (the locals tab), or in relation to the this pointer (the this tab).

The watch window (accessible via the view menu) allows variables & expressions to be constantly evaluated while single-stepping through the program. In this window, type month and year. As you step through the program you should notice the value of these variables being changed.
