Declaring Numeric Constants
声明数字常量
There are very few absolutes in life; however, I’m about to give you a C#
absolute: Every expression has a value and a type. In a declaration such as
int n, you can easily see that the variable n is an int. Further, you can reasonably
assume that the type of a calculation n + 1 is an int. However, what
type is the constant 1?
现实存在非常少的绝对,但是,我可以给你演示一个绝对,在c#上,
当你声明了一个n为int类型,那么随时的改变n的值,但它永远是int类型,即使是你n+1
,还是int类型,但是,对于一个永恒的1,该是什么类型,一个不能+的类型,永远不变的类
丛生到死(开始运动到退出)从来都是横守不变,也不可能被改变的类型
