  Zlggui is a simple gui. It took half a day to experiment with it. I personally think it is quite good to use this UI in a simple UI embedded system, which is easy to transplant, easy to modify. It implements basic draw lines, draw rectangles, draw

An LPC object is composed of zero or more variables controlled by one or more functions. In code, the order of function arrangement does not affect the object features, but the readability of the Code. When the object you wrote is called for the

I. BasicsThere is a well-known psychological formula for the conversion of color to Gray: Gray = r * 0.299 + G * 0.587 + B * 0.114 Ii. Integer Algorithm In actual use, it is necessary to use an integer algorithm to avoid low-speed floating-point

A pointer is a special variable. The value stored in it is interpreted as an address in the memory. To understand a pointer, we need to understand four aspects of the pointer: the pointer type, the pointer type, the pointer value, or the memory zone

Chapter 1. Pointer Concept A pointer is a special variable. The value stored in it is interpreted as an address in the memory. To understand a pointer, we need to understand four aspects of the pointer: the pointer type, the pointer type, the

Previous wordsThe training array is a dedicated array for processing numeric types (as its name, not all types) of data, originally used in WebGL, a ported version of OpenGL ES 2.0, which is presented in a Web page through the element. The

Typed arrays are an interface for JavaScript to manipulate binary dataSince the advent of the WEBGL project, the so-called WebGL refers to the interface between the browser and the video card, in order to satisfy the large and real-time data

Sockets are abstractions of communication endpoints. The file description descriptor is created with the open function, and the socket descriptive descriptor is created with the socket function. The socket function prototype is as follows:int socket

The C language switch statement is very powerful. However, it cannot be judged by a string, but only by a constant integer. This is understandable, because C's strings are just arrays, and they are not a whole.In some cases, it is useful to judge a

In a multithreaded environment, access to shared variables can be implemented using the lock free technology based on compare and swap, the benefit of which is high efficiency.An extract of atomic operation1.1 AndroidSource:

Number questionAre you able to answer the questions below? 0.1 + 0.2 = = 0.3 established? What does the. e-5 mean? How to express 8 binary? How do I convert into a system? How do I convert a string to a numeric or integer?

For a long time, VB has been ridiculed by some people because of its lack of perfect object-oriented support, lack of efficient error handling mechanism and poor performance. Vb. NET will completely change this situation. However, VB. NET in these

The first chapter. The concept of pointers A pointer is a special variable that is stored in a value that is interpreted as an address in memory. To figure out a pointer needs to figure out four aspects of the pointer: the type of the pointer, the

printf is probably the second function that many programmers come into contact with when they start learning C (I guess the first one is main), but it's an old friend, but do you know much about this old friend? Do you know much about his twin

When you construct various types of data into strings, the powerful features of sprintf rarely disappoint you. Because sprintf is almost the same as printf in usage, it's just a different destination for printing, which is printed to a string, and
