When you specify the C or C++ expression evaluator, you can use most Microsoft or ANSI C and many Microsoft C++ expressions as arguments to CodeView commands.
CodeView evaluates C and C++ expressions according to the same rules as the compiler, including operator associativity and order of precedence. There are, however, a few additional operators and some exceptions to the standard syntax. See the C Language Reference and C++ Language Reference for descriptions of C and C++ expression syntax.
