Compare different data types with zero values.

1. bool type: bool type variables cannot be directly compared with TRUE, FALSE, or 1 or 0. In the bool type, the non-zero value is TRUE, and the zero value is FALSE ). There is no definite value for TRUE. The value of VC ++ is 1, and the value of

Live555 class library

Live555 mainly has four class libraries: LibUsageEnvironment. lib; libliveMedia. lib; libgroupsock. lib; libBasicUsageEnvironment. lib After these four class libraries and related header files are imported to VC ++ 2010, you can easily implement the

Large and small ends, byte alignment

1) Little-Endian is the low-byte emission at the low-address end of the memory, and the high-byte emission at the High-address end of the memory.2) Big-Endian refers to the low address of high bytes discharged in the memory, and the low byte is

How to Use the union in C language to test the size-end mode of the system

First, parse the shared body and size mode. In the C language, several different variables share the same memory structure, which is called the "shared body" structure. The Memory Length occupied by the shared body variable is equal to the length of

A simple method to use qt Multithreading

Sometimes you need to call a very time-consuming api-class function in gui programming. If you do not use multithreading, the interface will become stuck. There is a very simple way to use multithreading. You do not need to create a new QThread

C language entry-05

Well, I have come to the fifth section without knowing it. In fact, we have already discussed C for more than half. As long as you have figured out the pointer concept, your C path has started, okay, let's continue to discuss pointers. Let's take a

Several Methods to reverse a single-chain table

Question: Enter the head node of a linked list, reverse the linked list, and return the head node of the linked list. The linked list node is defined as follows: struct ListNode{ int m_nKey; ListNode* m_pNext;}; Analysis: This is a

Qt learning path (2): Hello, world!

The first lesson of any programming technology will basically be Hello, world !, I also don't want to deliberately break this practice-as a matter of fact, we should first review the history of Qt, but even if we don't say this, it doesn't

Pointer understanding-

These two weeks are busy with the company, so there is no time to read the C language. OK. In the past few days, I discovered the pointer in the C language, in the past, I thought it was just a 4-byte book. It was used to store the address of an

Function pointer in C51

Function pointers are provided in the C language. In my opinion, an important function is to provide interfaces so that the C language can simulate an object-oriented language to provide interfaces for some functions and implement functional code

[Good Habit of programming] shielding Programming Language Features

Defining arrays is one of the most basic programming language functions frequently used for software development. The following example shows a simplified code that saves a session ID using arrays.# Define SESSION_ID_LEN_MIN 1 # Define

Qt learning path (33): internationalization (I)

The 2D drawing section has come to an end. I am still thinking about what to write in the following section. I planned to talk about the view-model issue first, but I saw a friend asking me about internationalization, so now let's talk about the

[Good Programming habits] reuse code to improve maintainability

Code reuse has two levels in software development. The first level is to reuse existing software modules when designing a new software function or developing a new project. This Reuse may be called better design reuse. Another layer is that when

Recursion or not recursion, That's a problem!

Today, the great gods in my class are excited and looking for books on this algorithm looks like they have a lot of classic examples. The great gods are blank in programming, so I am confused when I see the recursion part. For example, I used the
