Remarks
When you use the .expr command without an argument, the debugger displays the current default expression type.
The ?? (Evaluate C++ Expression) command, the Watch window, and the Locals window always use C++ expression syntax. All other commands and debugging information windows use the default expression evaluator.
For more information about how to control which syntax is used, see Evaluating Expressions. For more information about the syntax, see Numerical Expression Syntax.
