A circular diagram should be drawn up. Managed C+++. Never used to paint C++. Found arc(), but it only paints a full circle that can be filled with color. I found a pie function, but it's just a piece of "severe."
Tell me where to look. And, at least, a little tryout. I'll be grateful for any help.

"The general view of the masters, now the details should not be lost."
Please read more carefully the description of the function arc(...). There's a lot of stuff in the brackets.

Consider that you already have a table of comments (t1) with the necessary number of comments. You work with her, join her.SELECT http://t1.id , t1.id_user, t1.parent_id, t1.text, t1.date, u.avatar, u.username FROM comments t1 JOIN ( SELECT http://tt2.id FROM comments tt2 WHERE tt2.parent_id = 0 ORDER BY date DESC LIMIT ".$start.", ".$colCom." ) t2 ON t1.parent_id = http://t2.id or http://t1.id = http://t2.id LEFT JOIN users u ON t1.id_user = http://u.id ORDER BY t1.date, t1.parent_id ASC There's no need for extra fields on the domestic request, and there's only id pubic comments.

NET (net) platform, coupled with ADO.NET data access technology, is one of the best solutions for software development. It's very convenient to develop and clean. Reflected in terms of updating the individual elements of the project. A huge class library. Work on it is better paid (usually twice). The best IDE-MS Visual Studio cell I've ever tested is under NET. That's enough. But. It's expensive to start a platform. Given the cost of Windows server and family for ADO.NET MSSQL, very expensive. MONO (Link alternative .NET) is unlikely to reach the original in terms of productivity, staffing and stability.PHP. That the language that the platform, that the development tools leave much to be desired. If C# I could call one of the best languages, PHP is one of the worst, starting with the imperfect PLO and end up with strange designs.Nevertheless. PHP + Linux + Apache + PostgerSQL is a fully operational and fully free platform with a free comunit (which is important). I'm not adding as an alternative MySQL decision because I don't see a single plus in this CBD, but a minus is just a sea. The most significant plus PHP is the very low entry threshold. Every time, it's lower than for NET or Java. Accordingly, you can start work much faster if you start from scratch. Very demanded on the market.PHP Freamworths. Zend, Codeigniter, Kohana, Yii and other derivatives MVC-pattern. The difference between them is quite relative. The only thing you can say about Zend is that there's a lot more librarians in it than the others. There's nothing more Zend than alternatives. Personally, I've worked a lot with Kohana and a little less with the prototype cohana - CodeIgniter. A fairly good solution, a fast core, is all necessary to meet most of the library ' s tasks, CI has a strong focus on rapid action, Kohana is a great convenience of API. All these Framworths are in demand. Zend and CI more often than others. Java. Somewhere between the two categories discussed above. Compared quickly with NET, chronic chaos in libraries and decisions, with PHP (and free and in general opensor). What's not surprising is that it was done as a jug competitor, taking into account all the other mistakes. But if you need a free platform and good speed, there are no other alternatives. The main minus Java is to find a cooling suite or to build a server that's a little more complicated than for PHP and even NET. Required on an equal basis with NET.RoR (Ruby on Rails) - as does Java look like hybrid NET and PHP, but vice versa. This is an almost exceptional situation where we have a well-designed language and a rich class library in a free decision. Active Records from RoR are a dream of php señor. Disadvantages: bad hosting, slow. According to different tests, one of the slowest interpreters (at least slower than PHP). Less demanded.Python. Like Ruby and PCP is a crypt language (which means slow in performance). There are a few popular Freimvors: Django, TurboGears, Pylons, Zope. Everyone has a range of tasks that do well enough. It's not universal. It's still as chaotic as PHP and Java. Required on the same foot as RoR.That's how I see the question in person. I hope someone in my text will find it useful. Understanding the principled self-evidentity of the topic to the positive reaction of Guru, I don't expect to:

Users need to be grouped (many to many). For categories, rights are required by user groups (many to many). The realization of rights can be as complex (or simple).There is a lack of history of life-cycle applications, performances, etc. It can be implemented in the form of systemic and user comments (one to many). In principle, there may be several perpetrators. Application hierarchy.Life cycle, count. For each category it is. Categories - hierarchyWhen necessary, the date of establishment, the duration of completion, acceptances, labour-costs. ♪ ♪Less:Comment on applicationsApplication status (current status to be taken from history)That user status is not clearIf it's a teaching mission, you're gonna have to cut it off, take it.

QtCreator + qmake.Libraries can be assembled under different compilators or different versions of one compiler, for example msvc2010, msvc2013, msvc2015. The library is further equipped with a pri file indicating the way to the chemical and, depending on the compiler used and the compiler ' s version, the necessary lib/so files are connected.Ultimately, when we want to connect the library in the project, we just need to indicate the way to the pri file.Example of pri file:INCLUDEPATH += $$PWD/include DEPENDPATH += $$PWD/include !isEmpty(OUT_DIR) { LIBS += -L$${OUT_DIR} } else { LIBS += -L$$PWD/bin/$${QT_VERSION} } LIBNAME = DatabaseHelper2 LIBS += -l$${LIBNAME}$${STATIC_POSTFIX}$${MYCOMPILER_POSTFIX}$${DEBUG_POSTFIX} Example of project connection:include(D:/git_projects/DatabaseHelper2/DatabaseHelper2.pri) And create a common.pri where we identify variables:compileName=$$basename(QMAKESPEC) equals(compileName, win32-msvc2013) { MYCOMPILER_POSTFIX = _vc12 } equals(compileName, win32-msvc2010) { MYCOMPILER_POSTFIX = _vc10 } equals(compileName, win32-msvc2015) { MYCOMPILER_POSTFIX = _vc14 } DEBUG_POSTFIX = CONFIG(debug, debug|release) { DEBUG_POSTFIX = _d } STATIC_POSTFIX = contains(DEFINES, STATIC) { STATIC_POSTFIX = _static } And connect it first:include(D:/git_projects/common.pri) include(D:/git_projects/DatabaseHelper2/DatabaseHelper2.pri)

Problem.This error is due to the way the C++ indexing operator works, if we consult http://www.open-std.org/jtc1/sc22/wg21/docs/papers/2014/n4296.pdf in the Indexing section (translation and highlighting mine):5.2.1 IndexedA suffix expression followed by a bracketed expression is an indexed expression. One of the expressions should have the type “arrangement of T” or “point to T” and the other must be a type listed without context or integral. The result is of type “T”. The guy “T” must be a completely defined type. The expression E1[E2] is identical (by definition) to *((E1)+(E2)).This way of indexing makes C++ (and in /questions/tagged/c ) it is valid to index an arrangement https://es.wikipedia.org/wiki/Conmutatividad :arreglo[índice].índice[arreglo].So your object S has an indexing operator (mediate std::string) explicit and another implicit (and self-generate) that indexes a string of characters with a number. Why are they both candidates?By using a string verbatim (in your case "hola" and "mundo") this literal is a character arrangement and as such can be indexed. But to index we would need a number where do you get that number? From the conversion operator to Boolean!In C++ the boolean values can be implicitly converted to whole, so since the object S can be converted to boolean and this can be converted to integer and an integer can be used to index an arrangement, the compiler interprets:s["hola"] In this way:Convert s a booleano, for example with value false.Convert false a entero, with the value 0.Use the whole to index the arrangement "hola".Thus:0["hola"] Which is the same (by commutative property) as:"hola"[0] What is it? h.Solution.Indicates that conversion to boolean should be explicit, so you will prevent the compiler from using implicit conversions:struct S { int s; int operator[](const std::string &) { ... } explicit operator bool() const { ... } }; You can see the code running in https://wandbox.org/permlink/1yksr6XVOzUkakJE .

MSVC++ is grouping the virtual functions of one class by name of function. The sequence of teams follows the order of first appearance of a group function in the original file. Then within each group The order of performance shall be replaced by reverse (in relation to the order of declaration in the original file). The resulting order is the order in the virtual table.That's what you're watching in your case. I mean, you get two groups first.virtual void Call(int t); virtual void Call(wchar_t* t); virtual void Call(double t); virtual void F(wchar_t* t); (namely in this sequence of groups) and then the order within each group shall be reversedvirtual void Call(double t); virtual void Call(wchar_t* t); virtual void Call(int t); virtual void F(wchar_t* t); This will look like a virtual table in MSVC++++.So until you're overloaded, the virtual table will be posted. But as soon as you're in your class with the same names, that's how it starts.Such a group is, of course, only among the new functions of each individual class. If you add the same names in the last class, but with other signatures, all new functions in the virtual table will be added. after the functions of an ancestor. But again, among the added functions, grouping and reordering will be done in accordance with the rules described above.

Getting the symbol back from the function in any case. Another case, if you want to continue the cycle until the symbol is single. If so:char getChoice() { char choice; std::cout << "Hit or Stand?(h/s)..."; while ((std::cin >> choice && choice != 'h' && choice != 's') || std::cin.peek() != '\n') { std::cout << "Hit or Stand?(h/s)..."; if (std::cin.fail() ) { std::cin.clear(); std::cin.ignore(32767, '\n'); } std::cin.ignore(32767, '\n'); } return choice; } std:cin.peek() gives the following buffer symbol but does not count
