The following example shows the most basic functions and operations for points, vectors, and arrays, and these examples use three-dimensional objects, but most functions and operations apply to two-dimensional objects.For points and vectors, the default constructor initializes all coordinates to 0. They can also initialize individual coordinates at the time of creation, as follows:
Acgepoint3d P1 (2.0,5.0,-7.5), P2, p3 (1.0,2.0,3.0);Acgevector3d v1 (3

CTS and CLS
The CLS is known as the Common Language specification, which is used to define. NET language should adhere to the rules. The CTS is called a common type system, and it typically contains standard data types and so on.The CLS

the parameter. In this delegate, we can define the lbl_Status operation. For example, in the above example, I assigned the current accumulate result to the Text attribute of lbl_Status.
Then let's take a look at how to execute computing time-consuming operations in a walking thread, that is, the operation of the "start to accumulate" button:

Mainly use CancellationTokenSource to complete. The object has a cancellactiontoken. When startnew a task, the Toker can be passed to the created task. When CancellationTokenSource calls Cancel, the token state of the task will become canceled (Canceled) and the state of the task will become canceled. At this point, if the ta

When data is passed into a method, multiple return values can be returned for the method.
Parameter transfer
Value parameter. Data is transmitted by copying the value of the real parameter to the form parameter. The real parameter of the value parameter can be a variable or expression.
The following is a simple process of passing value parameters.

For a network diagram, the shortest path is the least-valued path of the edge weights passing between the two vertices, and we call the first vertex on the path the source point, and the last vertex is the end point. Dijkstra Algorithm

type of object. Objects of different classes can also be inserted into the same vector object. However, the inserted value should be an object instead of a numeric value, so be careful to convert the value to the appropriate object when inserting values.For example: To insert an integer 1 o'clock, do not call V1.addelement (1) directly, the correct method is:Vector v1 = new vector ();Integer integer1 = new

Defining functions in shell can modularize the code and facilitate code reuse. However, the scope of the variables in the script itself and the variables in the function may be confusing to you. Here, let's take a look at this issue.
(1) The variables defined in the shell script are global, and their scopes start from the defined place to the end of the shell or the deleted place.
