cstdint correct use

jules last edited by

I can't figure out the right use. cstdint♪ Like writing a type. uint32_t And I'm looking at his size in the programming of logic, then I'm on a platform where int > 32 and mine. uint32_t processing slowly. Okay, just use it. intwhich is always equal to the right value. If I move to another platform where int < 32the logic of my program will be hurt.
Maybe then we need to program the logic on the smallest. int and fix values uint_leastN_t/unit_fastN_t? Or sacrifice productivity?
And uint_leastN_t/unit_fastN_t - What are they different?

Types without reference fast or least Use exact size in battle. However, some architects of these types may not be present at all. As stated in Standard 18.4.1:
```
namespace std {
    typedef signed integer type int8_t; // optional
    ...
}
```
Therefore, the code has to be used, or fastor least A version. To achieve maximum speed or minimum memory flow, respectively. Such types are already mandatory in the Standard (no word available) optional)

You use WSHtpBinding - and this link means the use of WS‐Addressing standard, which in turn transmits the address of the host Party in the heading To.Honestly, I don't know why on the web service, where the sender and the receiver are always known, use WS‐Addressing. It likes stupidity, and it's because of it, SOAP thinks it's a pretty heavy protocol.So the simplest way is to give up WSHtpBinding and go to BasicHtpBinding, there's no such problem.If you need WSHtpBinding, that's three ways.The best in terms of standards is to tell the server what the real address is:var binding = new WSHttpBinding(); var internalUri = new Uri("http://192.168.1.10:8888/PService/"); var externalUri = new Uri("http://168.211.65.22:2145/PService/"); ServiceHost host = new ServiceHost(foo); host.AddServiceEndpoint(typeof(IFoo), binding, internalUri); host.AddServiceEndpoint(typeof(IFoo), binding, address: externalUri, listenUri: internalUri); I added two endpoints to enable the server to accept both direct requests and requests through NAT.But it's not a good idea to get the addresses straight to the code. <system.serviceModel> <services> <service name="ConsoleApplication.Foo"> <endpoint binding="wsHttpBinding" contract="ConsoleApplication.IFoo" address="http://192.168.1.10:8888/PService/" /> <endpoint binding="wsHttpBinding" contract="ConsoleApplication.IFoo" address="http://168.211.65.22:2145/PService/" listenUri="http://192.168.1.10:8888/PService/" /> </service> </services> </system.serviceModel> It's important that you don't mix it up. address - it's that the server will wait in To's headline, that's where the client sees the address. listenUri That's the address that actually listens to the server.The alternative is to teach the client to transfer the right titles. This is not a very good option, as it reveals to the client the internal structure of the server network. But for the completeness of the painting, I'll bring it, too.var binding = new WSHttpBinding(); var internalUri = new Uri("http://192.168.1.10:8888/PService/"); var externalUri = new Uri("http://168.211.65.22:2145/PService/"); var client = new FooClient(binding, new EndpointAddress(internalUri)); client.Endpoint.EndpointBehaviors.Add(new ClientViaBehavior(externalUri)); As I've already written, it's preferable to put the addresses in the configuration. For the client, this is done: <system.serviceModel> <client> <endpoint binding="wsHttpBinding" contract="ConsoleApplication.IFoo" address="http://192.168.1.10:8888/PService/" behaviorConfiguration="foo" /> </client> <behaviors> <endpointBehaviors> <behavior name="foo"> <clientVia viaUri="http://168.211.65.22:2145/PService/" /> </behavior> </endpointBehaviors> </behaviors> </system.serviceModel> As you can see, it's a little more complicated than a server, but it's still okay.A mixed version is also allowed. The thing is, the end-point address doesn't require it to be a real http address! All real web addresses are listed in the attributes listenUri and viaUrithe key requirement is a customer match and a server. Which means you can write any uri, like some kind of thing. urn:local:my-cool-web-service (this address is usually called referred to as a service address).This is an example of server and client configurations with a logical address: <system.serviceModel> <services> <service name="ConsoleApplication.Foo"> <endpoint binding="wsHttpBinding" contract="ConsoleApplication.IFoo" address="urn:local:foo" listenUri="http://192.168.1.10:8888/PService/" /> </service> </services> </system.serviceModel> <system.serviceModel> <client> <endpoint binding="wsHttpBinding" contract="ConsoleApplication.IFoo" address="urn:local:foo" behaviorConfiguration="foo" /> </client> <behaviors> <endpointBehaviors> <behavior name="foo"> <clientVia viaUri="http://168.211.65.22:2145/PService/" /> </behavior> </endpointBehaviors> </behaviors> </system.serviceModel> The dignity of this option is that no client knows anything about the details of the addresses. The disadvantage of this option is that if you show such a profile to the outside developer, he might, uh... be a little surprised by that decision.Finally, the last option. The simplest, but the crutch. You can turn off the address on the server's side:[ServiceBehavior(AddressFilterMode = AddressFilterMode.Any)] class Foo : IFoo { }

If the program only makes it all the time, it's gonna be loaded with a full ODE core of the processor. In order to load the two kernels completely, need to make two flows between which to separate the calculations and synchronize them somehow. This is the best example of parallel calculations. It is possible to program manual flows using the API of the operating system, using Boost type of wiring. Threads or C++11 flows. We could use some kind of fraamworth. This task is particularly convenient for the OpenMP.

I come to them that I have made some modifications to the code, went on a very difficult way, converted the object to string by JSON, until I chose to throw away everything I had done and eliminating the variables mat, opc, res. I made use of something more simple as it is:$("#Name").val($("#Name").val().trim()); the code is as follows:<script> $(function () { $(".field").change(function (e) { $("#save").show(); }); $("#save").click(function (e) { e.preventDefault(); var rows = $("#tablegroups tr").length - 3; $("#Name").val($("#Name").val().trim()); //console.log("<" + mat+ ">"); document.getElementById("frm_edit_subject").submit(); // $( "frm_edit_subject" ).submit(); }); $("#cancel").click(function (e) { e.preventDefault(); $form = $('<form action="<?php echo base_url() ?>index.php/gabby/materias" method="post"enctype="form-data" />'); $form.appendTo("body").submit(); }); $("#frm_edit_subject").validate({ rules: { "Name": {required: true, maxlength: 50}, "Scope": {required: true, }, "Status": {maxlength: 1, required: true}, } }); }); </script> <?php //print_r($materia); echo '<form id="frm_edit_subject" action="' . base_url() . 'index.php/gabby/materias" method="post"enctype="form-data" />'; echo '<div class="gbyTable" style="width:480px;margin:15px"><table>'; echo '<tr><td>Campo</td><td>Valor</td></tr>'; if (isset($materia['Subject_ID'])) echo '<tr><td>ID</td><td>' .

By the visa you want to make a query that results in AND for verification senha and email, that is, the SQL query you expect would be a type algorithm:SELECT * FROM post WHERE email = 'teste@email.com' AND senha = '123'; In this case we should do the following:routeradmin.post('/envlogin', function (req, res) { dadoslogin.findAll({ where: { [Op.and]: [ // usamos o "Op.and" dessa forma { email: req.body }, { senha: req.body.senhauser } ] }, raw: "true" }).then( function () { res.send("deu certo"); }).catch(function (error) { res.send("deu errado"); }); }); So Sequelize inferred that we want one AND for the two checks (email and senha), this generates:SELECT * FROM post WHERE (email = 'teste@email.com') AND (senha = '123');

Resolved, so I read in the documentation when the occurrence exists, in the case the email, the return on JSON must be false and not true as I was trying, I made the change and worked 100%. I did that.public JsonResult isExistEmail(String email){ Boolean isExist = dao.isExist(email); if (isExist){ return Json(false, JsonRequestBehavior.AllowGet); }else{ return Json(true, JsonRequestBehavior.AllowGet); } }

In /questions/tagged/c%2b%2b , formations1 they become implicitly pointers when they pass to a function.We can check with a code that prints the data types:template<typename T> void chivato(T) { std::cout << __PRETTY_FUNCTION__ << '\n'; } Yes to the function chivato We gave him a training, https://tio.run/##Ncw/C4JAGIDxufdTvNCgDoGterhEQYtFXENUHMd51IH3B30VQ/zslkPj7xkeFcJG1dK95nltnKq7SiMzvqVGS1sAkLahlqQZfYJ20mrkBfTeVKjeppfkY57giC1VWaZ8R8gYCnG@7Dm/icO13PHjqRRiydHDRTlOAMYRWmlcnMAIq0XDfZs@c1j9n0PyQ6OpaxymOUzz/AU :int x[10]; chivato(x); Print: void chivato(T) [T = int *]. So a training is passed as a pointer to a function, that means these two functions are equivalent:void función(int *f); // ^^^^^ <---- Puntero a entero void función(int f[]); // ^^^^^^^ <---- Formación de enteros The parameter int *f and the parameter int f[] They express the same: a pointer. So now we come to your function:void MaxMin(float *v[], int primero,int ultimo) // ^^^^^^^^^^ <---- ¿Qué es esto? Your first parameter is a formation ([]) of pointers to floating comma (float *), as we know that formations are pointers, we can conclude that the first parameter is a pointer to a floating comma pointer: float **. You probably wanted to do one of these two things:void MaxMin(float *v, int primero,int ultimo) // ^^^^^^^ <---- Puntero a valores en coma flotante void MaxMin(float v[], int primero,int ultimo) // ^^^^^^^^^ <---- Formación de valores en coma flotante 1Also known as arrangements or in English arrays.

When is found a \t, he advances to the next tab stop. And this varies according to the size that is configured in the terminal you are using.For example, in my terminal the size tab stop It's 8, so the exit was like this:Fahr: 0 Celsius:-17 Fahr: 20 Celsius:-6 Fahr: 40 Celsius:4 etc... What happens is that whenever there is one \t, he advances to the next tab stop, that in my case is every 8 characters. It would be something like that (the ruler below was blatantly copied inspired https://stackoverflow.com/a/13094746 0 8 16 24 |.......|.......|.......|... Fahr: 0 Celsius:-17 Fahr: 20 Celsius:-6 In the case, 0, 8, 16, etc are the Tab stops (always multiple 8, since the size in my terminal is 8).Then in the first case, the zero occupies position 6, and the \t is in position 7. Then he moves to the next tab stop, which is position 8.In the second case, \t is in position 8, so he advances to the next tab stop, which is position 16.In your case (assuming that the spaces shown are in this same way), it seems that the size tab stop It's 4, so you'd be like this:0 4 8 12 16 20 24 |...|...|...|...|...|...|... Fahr: 0 Celsius: -17 Fahr: 20 Celsius: -6 Now Tab stops are the multiple positions of 4.In the first case, zero occupies position 6, and \t is in position 7. Then he moves to the next tab stop, which is position 8.And in the second case, the \t is in position 8, so he advances to the next tab stop, which is position 12.A solution would be rather than depend on tab stop, simply set a fixed size for the numbers. For example, switch to:printf("Fahr: %-6d Celsius: %d\n", fahr, celsius); In the case, - says to align to the left, and 6 indicates the size to be used (and filled with spaces, i.e., both makes the size of tab stop, will always use this size). With this the output will be:Fahr: 0 Celsius: -17 Fahr: 20 Celsius: -6 Fahr: 40 Celsius: 4 Fahr: 60 Celsius: 15 Fahr: 80 Celsius: 26 Fahr: 100 Celsius: 37 Fahr: 120 Celsius: 48 Fahr: 140 Celsius: 60 Fahr: 160 Celsius: 71 Fahr: 180 Celsius: 82 Fahr: 200 Celsius: 93 Fahr: 220 Celsius: 104 Fahr: 240 Celsius: 115 Fahr: 260 Celsius: 126 Fahr: 280 Celsius: 137 Fahr: 300 Celsius: 148 But of course the exact sizes will depend on what you need. For example, if any number has more than 6 digits, it will be dismantled again:Fahr: 999999 Celsius: 555537 Fahr: 1000019 Celsius: 555548 But then you have to adapt the exit to each case. Anyway, the general idea and the explanation are there. You can see in https://en.cppreference.com/w/c/io/fprintf all available options accepted by printf.

http://php.net/manual/en/mysqli-result.fetch-all.php by default returns an array with numeric indices as shown in print_r() on the question. If you want this returned array if an associative uses the constant MYSQLI_ASSOC in the function call. If you want the return to be an accurate function object http://php.net/manual/en/mysqli-result.fetch-object.php together with a while.Change:return $sql->fetch_all(); To:return $sql->fetch_all(MYSQLI_ASSOC); The method current() Give it back array then you can access it like this:echo $r->current()['nome']; Or still: $item = $r->current(); echo $item['nome'] .' - '. $item['outra_chave'];

You are creating a class containing the variable guess. The problem is that within the methods of class you declare a other variable location with the same name. That is, if you change the value of guess in this method you will change the local variable (which will be destroyed when leaving the function) and not the class attribute. Remove int guess; from within the methods.
