As the name implies, a constant is a variable whose value is not changed during use. When declaring and initializing a variable, you can specify the variable as a constant by adding the keyword const before the variable:Const tax=0.06; Constants

Variable scope is a concept that many beginners can easily confuse.The scope of a variable is the area of code that can access the variable. In general, scoping follows the following rules:As long as the class is in a scope, its fields (also called

To be honest, read the Zhu Guangming C # video tutorial, feel a bit messy, but the general design of things are still there. I've integrated what I've been involved with in my own understanding.Zi Yue: "Learning and time learning, the joy?" "It's

C # provides a very practical way to provide energy, extension methods (Extension method)The extension method is to extend an existing type by an additional static method. By extending the method, you can do the related extensions you want to do

C ++ reference learning   0x01: simple reference C language is not referenced, c ++ is referenced, and programming is simplified Reference is essentially a pointer. An alias is given to an existing variable. sizeof is used to evaluate the size of
