Let's get down to the truth. Since it is the beginning, it is naturally a brief introduction to ASP. NET. Again, BlogBoy reminds readers that this series is a step-by-step process.

Variable (variable): The most basic storage unit in the program, including the variable name, type, scopeVariables should be declared, only after the system will allocate the corresponding length of storage space, the variable is essentially the name of the storage unitVariables are divided into local variables, member variables, constants. A local variable is typically a variable defined inside a method, and is initialized before it is declared.A member variable is also called an instance varia

Python, like C, has its own standard library, but in Python it's called a module, which is similar to a header file in C and a package in Java, where math is one of them, and the sin () and cos () functions are available in the Math moduleThe format for referencing modules in Python (in reference to the math example) is: Import MathFor an example that calculates the coordinates in the game:Import Math def = x + Step *= y-step * math.sin (angle)return nx,xyThis allows the return value to be obta

Gravity Field: the space in which the Earth's gravity acts. In this space, each point corresponds to a unique Gravity Vector.A variety of online games, whether 3D or the first perspective, or horizontal games (such as adventure Island), are required to simulate a gravity field.Let's take a look at Google's birth in Newton. the logo is replaced by an apple that falls freely.

1. What is git?
Git is a new Era version control system developed by Linux inventor Linus, what is a version control system? How to understand? A lot of detailed introductions on the web, but most of it is boring and difficult for beginners to understand, here I just give a few examples to help you understand.

probability of errors in your code is reduced.
Ensure forward compatibility. Use enumerations to reduce the probability of code errors when someone changes a value corresponding to a member name in the future.
In fact, to really elaborate, the enumeration is not simple, you can customize the function in the enumeration, you can implement the interface, these and other later encountered in the code to do a detailed introduction.At this point, the tutorial ends. You are welcome to contin
