Correct design of projects (programmes)

Are there any standards for designing programme projects? What's the right thing to distinguish modules? I'm doing one cheder, where all classes are interfaced; each class re-allocation is separate *.cpp; and the programme part is main.cpp. How is the standard?

Depends on the standard used, but Best practices - it's separate. header for each class and file .cpp / .ccwhose name coincides with header'ом♪
Same thing. http://google-styleguide.googlecode.com/svn/trunk/cppguide.xml This scheme has been approved.
In the case of small data structures, it is possible to combine some of these parts into one. header-файлbut I do not personally welcome this, because it's much easier to search the file by the name of the class.

You should get it.If you want to move on the sidelines and take out all the bikes by dividing their point, you need to split the number to the bayta first. How to do that depends on the exact type. Like, maybe.var bytes = BitConverter.GetBytes(number); (LAUGHS) number should be number, not line. If it's a line, we'll have to pre-refer it to the right type.)Then one can encrypt each byte:string.Join(".", bytes.Select(b => b.ToString("X")); If you need to transfer the entire number to the " big " line 16, do as it says. https://ru.stackoverflow.com/a/416733/10105 ♪If you have to count the number on your record, we're doing this:We'ash the line on the parts:var parts = s.Split('.'); Each part shall be determined:var bytes = parts.Select(p => byte.Parse(p, NumberStyles.HexNumber)); And stick it in the numbers. Because you've got 8 bytes, that's fine. ulong:var result = BitConverter.ToUInt64(bytes.ToArray(), 0);

Programme out 01 'Cause she's supposed to be. 01♪ Language specification http://eel.is/c++draft/dcl.link#6 Two declarations for a variable with C language linkage with the same name (ignoring the namespace names that qualify it) that appear in different namespace scopes refer to the same variable.Two declarations of variables with the same name C-link ( disregarding the qualifying names of the domains of names) that are located in different domains of names refer to the same variable.Both announcements - A::x and B::x - declare the same variable.The questioning itself is somewhat surprising. Under what circumstances could such a withdrawal programme be expected 00? If I could. A::x and B::x Have you declared different variables? But then the program wouldn't have been compromised because of the lack of a definition. B::x♪

I sort of figured it out and I did, but whoever wrote the code on the question is very advised to read the code format.It's also not clear what you've been trying to achieve:int res=processLine(input,output1,false); You're calling for a function. two You give her an argument. Three.and then you try and reset the type string Apply a type change int (sighs)int Type of whole data Chisel) Read the type of data and understand that there's no way to put anything in. int♪I did without QT chips, like QString or QChar♪ ♪ main Text processing function, result recorded in file output.txt♪ You tried to read the file, calling the processing function, and having only the name of the file (but not the file itself), and then the result was to put it in the variable. int and waited for the file. output.txtwhich is not yet available (name only) will be the text. This function does not read or record anything in the file. And the fact that you give her the names of the files you need is that you don't need anything. She'll just process names and get them back. And actually, better like I said. Andrej Levkovitch First learn your tongue and then write the code.Same file. ouput2.txt The same text processed is recorded, but vice versa.#include <iostream> #include <cctype> #include <fstream> using namespace std; const string separators = "\n !@:?#$%^&*()_+{}\|/,.!-"; bool isSeparator(char ch) { return separators.find(ch) != string::npos; } const string digits = "0123456789"; bool isNumeric(char ch) { return digits.find(ch) != string::npos; } string reverse(const char* charstr) { string result=""; for (int i = sizeof(charstr) - 1; i >= 0; --i) result += charstr[i]; return result; } string processLine(string line, bool rev) { string word(""), new_line(""), result(""); char prev_c('\n'), c; unsigned long long len = line.length(); for (unsigned long long i = 0; i <= len; ++i) { c = i < len ? line.at(i) : '\n'; if (isSeparator(c)) { if (isspace(c) && ((word.length() == 0 && new_line.length() == 0) || isspace(prev_c))) { // пробелы в начале или несколько пробелов между словами - ничего не делаем } else { if (c == '-' && i + 1 != len && isNumeric(line.at(i+1))) { // это число со знаком минус word += c; } else { if (word.length() > 0) { if (rev) { //std::reverse(word.begin(), word.end()); word = reverse(word.c_str()); } new_line += word; } if (c == '.' && isspace(prev_c)) { // нужно удалить пробел перед точкой new_line.erase(i - 1, 1); } if (c != '\n') new_line += c; if (c == '.' || c == '\n') { if (new_line.length()>0 && new_line!=".") result += (new_line+'\n'); new_line=""; word=""; } word = ""; } } } else word += c; prev_c = c; } if (new_line.length() > 0) result += new_line; return result; } int main() { string input = "input.txt"; string output = "output.txt"; string output_2 = "output2.txt"; ifstream file(input); if (!file.is_open()){ cout << "Error while opening the input file."; return 1; } ofstream out_file(output); if (!out_file.is_open()){ cout << "Error while opening the output file."; file.close(); return 1; } ofstream out_file2(output_2); if (!out_file2.is_open()){ cout << "Error while opening the output 2 file."; file.close(); out_file.close(); return 1; } string tmp = "", res; while(getline(file, tmp)){ res = processLine(tmp, false); out_file << res; res = processLine(tmp, true); out_file2 << res; } out_file.close(); out_file2.close(); file.close(); cout << "Programm finished successfully"; return 0; }

Monitored many projects on different hosts (specially by reading this issue) identified certain requirements.The average OES consumption per page for the generation of one page (php) comes out of 7864320 machine words (15Mb, correct if wrong), twice as much as the rest.We'll count for about a bunch of tats to calculate the shit that goes to the lake, = for 64 architectures (64 BT,8 Byte(16 MS) per tact) we consider one operation on data block 7864320/16 = 4,91520 tt.Now we think how many Germans need to have one laser for each click(s/time between clicks approximately seq.) = 4,91520 Germans (oper/sek) = 491.52 klogerz =~ 0.5 megahertz. (Fuckle if wrong with transfer)Doesn't sound like the truth. MHz rounds up to 0.25-0.05. Tell me where the colic is in the calculations = The channel is equal to the total weight of the web page. The page weighs differently. I saw five metres on average. Consistent channel =~ 5 meters/time between clicks.Total = 15Mb RAM/0.15MHz/5Mb/s per day per camp. OS = Better on a yard like Linux/WinNT.

In the field android:layout_below id must be without "+"<ScrollView android:layout_width="match_parent" android:layout_height="match_parent" android:layout_below="@id/app_bar"> Okay. "+" means a new id is being created:IDAny View object may have an integer ID associated with it, to uniquely identify the View within the tree. When the application is compiled, this ID is referenced as an integer, but the ID is typically assigned in the layout XML file as a string, in the id attribute. This is an XML attribute common to all View objects (defined by the View class) and you will use it very often. The syntax for an ID, inside an XML tag is:android:id=@+id/my_button"The at-symbol (@) at the beginning of the string indicates that the XML parser should parse and expand the rest of the ID string and identify it as an ID resource. The plus-symbol (+) means that this is a new resource name that must be created and added to our resources (in the R.java file). There are a number of other ID resources that are offered by the Android framework. When referencing an Android resource ID, you do not need the plus-symbol, but must add the android package namespace, like so:Android:id/emptyMaybe he just doesn't find a resource app_bar? Below which is to be located because of the new id being created for him?

1. GOST 19.701-90 does not contain separate symbols for transfer between pages, as was the case in the older GAS, and therefore the porting number should be completely unique within the algorithm.2. The call for a remote is usually set up by a block of "3.2.2.1. Predetermined process or 3.3.2.1. Transmission of control (the second symbol can only be used in different programme interaction schemes).The algorithm itself is a regular algorithm. Terminal symbols can spell "Preparations" and "Supplementary End" instead of the usual "People" and "The End." If the use of structural exemptions is implied, the subprogramme may have a second output, error.The transfer of parameters to the dilgorithm inside the algorithm looks like a normal symbol "3.1.1.1. Data, same as the return value. The fact that this is the parameters and the value to be returned is required to be stated inside the symbol.Another option for deleting is a detailed presentation, paragraph 4.1.8. At the top of any symbol, a horizontal strip may be painted indicating that the symbol is more detailed elsewhere. The detailed presentation is presented in the same way as the subprogramme, except that no parameters are clearly introduced by the symbol " 3.1.1.1. Data, instead, inside the "accessable" symbol all the variables that are outside.Your block of "declaring data from the file" would be a symbol of "3.1.1.1. The data's with the strip.

From a git point of view, it's just a separate repository. It is important to structure the project accordingly.You're distributing a piece of work to a separate library or even a service. I'll tell you about the library.For the library, you create separate git repositories. The developer works with him, tests the library itself in isolation. Once the changes are made, the new version is published (this may be a purely test version). This requires a publication procedure. It could be some kind of crypt that collects the library and publishes it in the internal artifact repositories.For java ecosystems, it could be maven repositories, for python - pypi, for nodejs - npm repositories, I think the idea is understandable.The remaining libraries/modules use the library exactly as other libraries, i.e., the name and versions of the dependents. Further, this internal repository should be connected to the dev/test environment for assembly, i.e., to use a new published version.The users of this library, other module developers or a system that makes deployment on a test environment, can now use a new published version. That would require dependent modules to change and indicate a new version.This is the way to test the integration of the new library.

What modules are, what classes in every module they're responsible for.Well, let's just say you're going to draw up such a detail... What's next? What do you want? What's the point, who's gonna keep her in the right state?From personal experience. If a project with this quality of the code is involved, it is either necessary or de facto to produce a normal appearance (if there is time) or to write comments so that the class can be read about.However, even if there is time to re-activate, the programmer must comply with all the famous doctor's orders: "Don't hurt!"A, in order to avoid harming, it is highly desirable to gain knowledge and experience.It is true that, in addition to the development itself, the work process should generally be organized in an appropriate manner, but that is already more within the competence of the management, starting with the timlide.Is there any good books about this?They're even in Russian. Open for yourself S. McConella and R. Martina, M. Faulera, etc.

This error is happening because the parse method of the class SimpleDateFormat returns a Date of the java.util package and you are trying to make cast for a java. sql. Date.You can resolve this by making explicit which Date you use and you will not need to cast. java.util.Date date = new SimpleDateFormat("dd/MM/yyyy").parse(dataEmTexto); or changing the import in the AddContatoServlet class to java.util. date,then you can use it that way.Date date = new SimpleDateFormat("dd/MM/yyyy").parse(dataEmTexto);
