Embedded statements are not allowed in constant expressions, such as the value of an enumeration constant, the width of a bit-field, or the initial value of a static variable.
在常量表达式，比如枚举型常量、位域的宽度或是静态变量的初始值，是不允许使用在这种声明中的。
Because constants are an important building block for constructing expressions, it is important to be able to write constant values for each of the basic data types.
因为常量对于构造表达式非常的重要，所以学会书写每种基本数据类型的常量就显得至关重要了。
