embedded language. At the same time, another declarative language is added to a different application for data description. Therefore, we decided to combine the two languages and add the data description function to the Lua programming language. Lua has surpassed its original purpose and is used in other industrial projects.This document describes the design decisions and implementation details of Lua.--------------------------------------Extended language--------------------------------------T
reusable Object-Oriented Software
Erich Gamma, Richard Helm, Ralph Johnson, and John M. vlissides
This book describes various object-oriented design patterns. For each of the 23 modes in the book, the author provides in-depth analysis, which includes clear examples, common defects, and related models, sample code written in C ++ or smalltalk. These modes cover the single-piece mode, observer mode, template method mode, iterator mode, and proxy mode.
This book is a required bibliography for int

Intersection of multiple line segments on the plane.For N line segments on the plane, if the most direct method is used, that is, the intersection of the two, then (N-1) + (N-2) +... 1 = N (N-1)/2 operation, time complexity is O (n2 ). This method is feasible when the number of intersections is close to n (N-1)/2, but in most cases, the number of intersections formed by N line segments is small, in

This is very commonAlgorithmSee classical algorithm books (or classical interview books) such as the beauty of programming and the pearl of programming :)). There are a lot of discussions and implementations on this issue on the Internet. I would like to write down my understanding here. Some people may have written it before, but after all, it is something I think about and I should record it.

following code:
// Based on the above Code
// The original first element is BMW.
// After the value is assigned again
// The value of the first element of the array is Bentley.
Mycars [0] = "Bentley ";
After learning about the basic usage of arrays, let's take a look at several methods of arrays. For details, see the following:1. Use the Concat () method to merge two Arrays:

Before talking about this post, I have to repeat Joshua Bloch's suggestion: if you have not readProgramming pearls(The Chinese version is called programming Pearl.) read this book now. If you read it once, read it again now.
Or back to Joshua's article. Jon Bentley, the author of programming pearls, gave a lecture on CMU. He asked the doctoral students in the computer departme

Details:The tfw file is a text file about the coordinate information of TIFF images. ArcInfo, microstation, and AutoCAD all support coordinate information files in this format. This file defines the affine relationship between pixel coordinates and actual geographic coordinates of an image. The basic principle is as follows:
X' = AX + by + cY' = dx + ey + F
Where:
X' = geographic X coordinates of pixels
Y' = geographic y coord
How to open a DWG file? What can be used to enable the DWG format? How to open a DWG file? Today, we recommend several widgets to preview and edit files in DWG format.
Cadviewx is a powerful CAD file and Image Browsing library. in environments that do not require third-party software, it provides CAD preview controls, CAD printing, CAD files, and other format pictures, you can also drag or zoom in the mouse. The editing control supports AutoCAD DWG, DXF, and all versions of the files.
