C++ is a language that gives freedom to do powerful and flexible things. And that requires a lot of responsibility to manage all resources.When you install an object there are basically two operations: the allocation which is made by the operator https://pt.stackoverflow.com/q/237588/101 , and this can be customized in the type that is creating with overload of operators; and construction that is customized to us https://pt.stackoverflow.com/q/73530/101 , which are static methods, that is, are part of the type and that will initialize the data in the object being created. In addition to data startup can perform certain algorithms and work with features external to the application, such as operating system services for example.This object has a https://pt.stackoverflow.com/q/135572/101 determined by a number of factors. At the time the object must cease to exist if it has a destructor method it is called (it is placed by the compiler at the appropriate location, or is invoked by the library or manually called by the programmer). This is method, which is virtual, can, or should, release the resources acquired externally, perform some finishing algorithms and release the memory allocated through the https://pt.stackoverflow.com/q/152765/101 . If you don't do this, you'll have "hanging" and https://pt.stackoverflow.com/q/174916/101 . So without this method or without it doing the proper operations you will have problems.O ~ as prefix in the name was convinced to be the destroyer, only to differentiate from the constructor that has the name of the type equal to the destroyer.In his example he is releasing the memory of two vectors. But that code is wrong. Never allocate by one method and release by another. In the case was allocated with malloc(), then should use free(). Or else I should have stayed with new to release with delete that is the most correct in C++. Even the most similar part of C++ uses a 90s style, C++ has changed a lot here. The code was written by someone who does not understand C++ right.See https://pt.stackoverflow.com/q/321651/101 . Or in a more abstract context than they are: https://pt.stackoverflow.com/q/75613/101 .

Because, p, you have an index to class, and q is an index to the index. In the second case, you're trying to assign a class index to the indexer, and in the first address of the index.

For standard withdrawal flows, there is a overloaded operator https://en.cppreference.com/w/cpp/io/basic_ostream/operator_ltlt2 accepting as a parameter const char*♪ This overload is necessary for the removal of zero-terminated C-stroke, which is what's going on in your program.If the index itself has to be decorated char*enough to lead him to the type const void*:cout << static_cast<const void*>(&str[i]) << "\t";

According to function documentation http://www.cplusplus.com/reference/cstdio/sprintf/ :The size of the buffer should be large enough to contain the entire resulting string (see snprintf for a safer version). https://pt.stackoverflow.com/questions/161673/problema-com-manipula%C3%A7%C3%A3o-de-arquivos-txt-em-c#comment332466_161673 the size of buffer It is 4, you are trying to save at least 10 characters... You can increase the capacity of buffer, for example http://www.cplusplus.com/reference/cstdio/FILENAME_MAX/ or use the function http://www.cplusplus.com/reference/cstdio/snprintf/ , where the maximum number of Bytes that will be written, so: char nome[FILENAME_MAX]; // ... snprintf(nome, FILENAME_MAX, "Data_%d.txt", i); // .... http://ideone.com/8CmuKy

Flag -Ofast Not recommended because it is considered unsafe (includes optimization that violates compatibility with the standard).There's a bunch of different flags, but using them depends on the target architecture and mind.I often use the following set to maximize the value of the application on architecture x86:-march=native -O3 -mfpmath=both -funroll-loops -fopenmp -floop-parallelize-all -D_GLIBCXX_PARALLEL -D_GLIBCXX_MERGESORTThey do not require user intervention in the programme code.

The compilation is done in what you have to do if you do not send it does not compile. In fact no normal compiler compiles dependencies if he does it is not just a compiler. In general there is a system of build that does this task and in many cases need to write scripts to indicate about the dependencies. You can see more about in https://pt.stackoverflow.com/q/154102/101 . C and C++ uses https://en.wikipedia.org/wiki/Make_(software) .For example, if I include a certain library in my program, when it is compiled, I will pass them to the compiler, correct?Generally, yes.But now, after compiled the program, it would work without me having installed on my particular library machine?It depends. If it's something that's already on the operating system, you don't need it. If it is something that only serves your application then in general you have to send along or pre-install. But this is not worth generating a monolithic executable, see more in https://pt.stackoverflow.com/q/149372/101 .It can also be useful: https://pt.stackoverflow.com/q/44269/101

There is no solution in this general way. The ability to complete the data in the existing file is in fact not possible for most audio formats because it involves a combination of multiple factors: the structure of the file should include the possibility of adding to or avoiding the need to match the data formats of the existing and new part; the implementation of the container should be clearly adapted to the label; in most cases, implementation will involve a combination of all the fragments available before the first batch can be written, often.Of the traditional data formats, there are only a small number of examples, such as MPEG TS, where there is a fundamental requirement for subscription. The standard sticker comes from the already ready pieces and through the full redesign of the copy file.

We're adding to the virtual hospice file:RewriteMap lc int:tolower After which, add the following entries to .htaccess:RewriteEngine On RewriteBase / RewriteCond %{REQUEST_URI} ^[^A-Z]*[A-Z].* RewriteRule ^ ${lc:%{REQUEST_URI}} [L,R=301] Second version of such rules:RewriteEngine On RewriteBase / RewriteCond %{REQUEST_URI} [A-Z] RewriteRule (.*) ${lc:$1} [R=301,L] Mode 2 is the most cumbersome but not required access to Apache construction. Suffice to add the rules to .htaccess:RewriteEngine On RewriteBase / If there are caps, set HASCAPS to true and skip next rule RewriteRule [A-Z] - [E=HASCAPS:TRUE,S=1] Skip this entire section if no uppercase letters in requested URL RewriteRule ![A-Z] - [S=28] Replace single occurance of CAP with cap, then process next Rule.

Once the auspictarter made the proposed comment, write it as an answer.Shablon: (?<=-ID).+(?=\.html)Demonstration: This regular expression is searched for a text concluded between -ID and .html♪ It's true if there's a combination of symbols in the reference somewhere. -ID, well, there's no way that the pattern's gonna work on it. https://regex101.com/r/qX8eT4/2 ♪ I hope that no such reference will be made to the author..+ - any other than the handing over of the line, a symbol repeated one or more times.-ID and \.html - literature -ID and .html respectively. Point before html It must be screened to act as a literary and not to use a text that replaces a point with any symbol other than the port of the line, like IDSashaBrilliantFhtml or IDSashaBrilliant7html ♪ https://regex101.com/r/qX8eT4/3 ♪?<= and ?= - Operators look back and look forward, respectively. We found the expression. -IDSashaBrilliant.htmlbut -ID and .html We do not need; in order not to consume them, the data of the context searchers are used.Finding contexts can be read in Ben Fort's book, "Regular expressions. 10 minutes class 9, page 111.
