Review above:In the previous article, I introduced how to create a package file and create a custom project. Next I will introduce wxwidget installation as agreed. This article is applicable to the dev-CPP and mingw32 compilers. Chapter 4 download and install wxwidget This chapter describes how to download and install the wxwidget GUI development library.First, we need to know that wxwidget is used in Win32. Therefore, we need to download the wxmsw de

Dev-CPP/mingw32 Environment Introduction (12) Review above:In the previous article, we learned how to set and use GTK in mingw. From this article, we will begin to enter the intermediate article. That is to say, we mainly use mingw and other GCC in Win32. Instead of introducing only those operating IDE and installing components. If we used to be on the runway, we are about to take off now. Therefore, we will pay more attention to program configuration

This afternoon, ubuntu (I am using Ubuntu 9.10) is very useful. It is a good operating system for Linux beginners. Since I have just been familiar with C ++, I cannot help writing C ++.ProgramEnthusiasm. So I wrote a very simple C ++ program. Code:( Hellocpp. cpp) 1 # include 2 void main (){3 using namespace STD;4 cout 5} Then compile g ++ hellocpp. cpp-O hellocpp Error: Hello.

After the upper is called, all characters in the string executed by the src parameter are converted to uppercase letters, and the structure is placed into the desc string. Write The program test1 calls the upper function i

Dev-CPP/mingw32 Environment Introduction (11) Review above: In the previous article, I introduced you to the installation and Setup of SDL. I hope you will be able to benefit from this, as stated last time. This time we will install the GTK runtime and Development Library. Of course, this is all done under Win32. I hope you will fall in love with this. Chapter 4 download and install GTK GTK? Many may wonder why GTK is required when MFC is available? I

Review above:In the above section, we mainly introduce how to create a custom project in Dev. The structure of the package is briefly introduced later. Next I will complete the preparation of the package. Chapter 2 Dev-CPP package preparation First, let's take a look at the dev-CPP package. The Dev-CPP package has the following features: Of course, I am struc

compiler will define this protector and run the code block compilation! Until you meet #endif. The next time you encounter this protector, you will not run the code block compilation. This mechanism guarantees that the compilation will not be repeated. in practical use, I found that a single CPP file multiple include in the same. h header file or header file several times include a header file, there is no problem. However, this can be problematic w

In the class, I saw the teacher compile the CPP file with Cl commands in the DOS environment. Come back and try it. Wow, I can't help it... In the past, we had to set something called environment variables... Method 1: Find the vc98 \ bin \ vcvars32.bat file in the VC installation directory, open the CMD command prompt, drag it in, and press enter to get it done! However, it seems to be temporary and not verified. It's just fun. After all, the black

Today, the downloaded opencv mixed Gaussian modeling routine encountered the following error: Fatal error c1083: cannot open source file: 'd: \ Program Files \ Microsoft Visual Studio \ vc98 \ MFC \ SRC \ appmodul. CPP' Originally, we created an MFC project. The MFC engineer needs to call the winmain () function, which is placed in appmodul. in the CPP file, the problem here is that the appmodel cannot be

Problem description: Chinese poster-man problem, CPP for short, provides a connected graph and asks the minimum path to be taken after each edge at least once with the same start point and end point. Undirected graph CPP 1. Consider that when all vertices are even numbers, this figure is the European Union, so any Euler's circuit is the answer. 2. when two vertices are odd, you only need to find the shortes

My version is 4.9.9.2. Other versions may be correct, or they may only occur on my computer. I cannot remember it. It seems that it cannot be installed in the "Program Files" file during installation. Due to space, I installed it in the "C:/dev-CPP" directory. At the beginning, I do not know why some projects do not respond when I click the "run" button after compilation. Today, we suddenly found that all the paths are English characters, and Chin

Header file (. h): Write the declaration of a class (including the declaration of members and methods within a class), function prototypes, #define常数等, but generally do not write specific implementations. When writing header files, be aware that the following styles must be added to the beginning and end of the precompiled statement (below): #ifndef circle_h#define Circle_h//your code is written here.#endif This is done to prevent duplicate compilation, and failure to do so can be an err

"iOS development". H,.m,.mm,.cpp and other differencesFile differences:. h: Header file. Header files contain declarations of classes, types, functions, and constants.. m: Source code files. This is a typical source code file extension that can contain objective-c and C code.. MM: Source code files. Source code files with this extension can contain C + + code in addition to the OBJECTIVE-C and C code. This extension is only used when you really need t
