There is a problem here because comma operator will be treated as a separator of parameters of macro. To avoid this, the comma operator should be screened inside matched pairs of parenthesis . And a statement expression has a natural pair of them. ...
You can also convert values from one type to another explicitly using the cast operator (see Chapter 5): (type_name) expression In the following example, the cast operator causes the division of one integer variable by another to be performed as a floating-point operation: ...

As the preceding example shows, you always use parentheses in a target-typednewexpression. If a target type of anewexpression is unknown (for example, when you use thevarkeyword), you must specify a type name. Array creation You also use thenewoperator to create an array instance, as the...
