If a dynamic mass means an index initialized by the type code
```
int* array = new int[42];
```
No way.
In some exercises, the size can be challenged https://msdn.microsoft.com/en-us/library/z2s077bc.aspx /msize/malloc_size, but the standard does not specify:
```
#include <malloc.h>
int main()

{

int *arr = new int[42];

int length = _msize(arr) / sizeof(int); // 42!
return 0;

}
```

lineWrapMode : LineWrapMode This characteristic contains the regime for the transfer of the lineThe default regime is WidgetWidth, which makes words move on the right edge of the edited text. The transfer takes place on the lacunae, keeping the words intact. If you want to move words, use the setWordWrapMode(). If you have a FixedPixelWidth or FixedColumnWidth mode, you should also cause setLineWrapColumnOrWidth() with the desired width.from PyQt5 import QtCore, QtGui, QtWidgets class Ui_MainWindow(object): def setupUi(self, MainWindow): MainWindow.setObjectName("MainWindow") MainWindow.resize(228, 106) self.centralwidget = QtWidgets.QWidget(MainWindow) self.centralwidget.setObjectName("centralwidget") self.verticalLayout = QtWidgets.QVBoxLayout(self.centralwidget) self.verticalLayout.setObjectName("verticalLayout") spacerItem = QtWidgets.QSpacerItem(20, 1, QtWidgets.QSizePolicy.Minimum, QtWidgets.QSizePolicy.Expanding) self.verticalLayout.addItem(spacerItem) self.textEdit = QtWidgets.QTextEdit(self.centralwidget) self.textEdit.setMinimumSize(QtCore.QSize(0, 50)) self.textEdit.setSizeAdjustPolicy(QtWidgets.QAbstractScrollArea.AdjustToContents) self.textEdit.setObjectName("textEdit") self.verticalLayout.addWidget(self.textEdit) self.comboBox = QtWidgets.QComboBox(self.centralwidget) self.comboBox.setObjectName("comboBox") self.verticalLayout.addWidget(self.comboBox) spacerItem1 = QtWidgets.QSpacerItem(20, 1, QtWidgets.QSizePolicy.Minimum, QtWidgets.QSizePolicy.Expanding) self.verticalLayout.addItem(spacerItem1) MainWindow.setCentralWidget(self.centralwidget) self.retranslateUi(MainWindow) QtCore.QMetaObject.connectSlotsByName(MainWindow) def retranslateUi(self, MainWindow): _translate = QtCore.QCoreApplication.translate MainWindow.setWindowTitle(_translate("MainWindow", "MainWindow")) self.textEdit.setHtml(_translate("MainWindow", "<!DOCTYPE HTML PUBLIC \"-//W3C//DTD HTML 4.0//EN\" \"http://www.w3.org/TR/REC-html40/strict.dtd\">\n" "<html><head><meta name="qrichtext" content="1" /><style type="text/css">\n" "p, li { white-space: pre-wrap; }\n" "</style></head><body style=" font-family:'MS Shell Dlg 2'; font-size:8.25pt; font-weight:400; font-style:normal;">\n" "<p align="center" style=" margin-top:0px; margin-bottom:0px; margin-left:0px; margin-right:0px; -qt-block-indent:0; text-indent:0px;">Образец текста Образец текста Образец текста Образец текста Образец текста Образец текста </p></body></html>")) class Window(QtWidgets.QMainWindow, Ui_MainWindow): def init(self, parent=None): super().init() self.setupUi(self) self.textEdit.setLineWrapMode(QtWidgets.QTextEdit.NoWrap) self.textEdit.setHorizontalScrollBarPolicy(QtCore.Qt.ScrollBarAlwaysOff) self.textEdit.setVerticalScrollBarPolicy(QtCore.Qt.ScrollBarAlwaysOff) self.textEdit.setFixedWidth( self.textEdit.document().documentLayout().documentSize().width() + self.textEdit.width() - self.textEdit.viewport().width() ) if name == 'main': import sys app = QtWidgets.QApplication(sys.argv) w = Window() w.show() sys.exit(app.exec_()) UpdateI don't understand why you won't tell me what's wrong with my answer?

It's pure math.What is the maximum amount of physical memory that can be installed?2 (the amount of values a 1 may have) raised to 16 (the amount of bits available) gives 65536, or 64KB.What is the maximum amount of virtual memory that can be accessed?Here is 2 high to 24 that gives 16MB.The other information is irrelevant to these questions.

Let's get something clear. int *i It's a variable type. Int♪ When you write delete i; You don't remove the variable, you remove what it points. In other words, it is possible to:int *i = new int; delete i; i = new int; Because you work with a variable type. Intwhich is intact.You can't do that.int *i = new int; delete i; *i = 42; Because you work at the variable type. intwhich was removed.Now that we've clarified this, it's automatically clear with the first question. Yes, you can. You created statistical variable type indexand initiated it by a variable type indicator intwhich is located Dynamic memory

You have 3 ways to give that image size or style. That if, you know that adjusting image size by photoshop or other application is ideal for you to occupy the minimum file. Since an image of 1900px X 1900px modified by CSS to 50px X 50px is visualized small but occupies just as 1900px X 1900px with the consequence it has (occupy space, delays loading, etc.). Therefore first I recommend adjusting the size of the original file.To match the size by CSS or give you other interesting styles such as border or transparencies, you can do in 3 different ways:1) CSS Styles In the same label IMG<!DOCTYPE html> <html> <head> </head> <body> <img style="width:50px; height:50px;" src="imagenes/imagen1.jpg"/> </body> </html> 2) CSS Styles In the head <!DOCTYPE html> <html> <head> <style type="text/css"> img{ width:50px; height:50px; } </style> </head> <body> <img src="imagenes/imagen1.jpg"/> </body> </html> 3) CSS Styles by Linked External File <!DOCTYPE html> <html> <head> <link href="css/estilos.css" rel="stylesheet" type="text/css"> </head> <body> <img src="imagenes/imagen1.jpg"/> </body> </html> With the file for example called styles.css for example in a directory in the root called css, for the route to be indicated: css/estilos.cssAnd in its content:img{ width:50px; height:50px; } What if I have 2 or more IMG I want to give you different size or style?You can observe that in case 2 and 3 we used the same img label as an identifier to give it the css style. If there is a single image there is no problem, but if you have 2 or more images you want to give different sizes, this way will have given you the same size to all the elements with img label. To avoid that you can add to each element or tag img an id or class identifier to then give different style to each image or element. I give you the examples:4) CSS Styles In the head with CLASS ID on the IMG label <!DOCTYPE html> <html> <head> <style type="text/css"> .imagen1{ width:50px; height:50px; } .imagen2{ width:60px; height:60px; } </style> </head> <body> <img class="imagen1" src="imagenes/imagen1.jpg"/> <img class="imagen2" src="imagenes/imagen1.jpg"/> </body> </html> 5) CSS styles using external file linked with CLASS identifier on the IMG tag<!DOCTYPE html> <html> <head> <link href="css/estilos.css" rel="stylesheet" type="text/css"> </head> <body> <img class="imagen1" src="imagenes/imagen1.jpg"/> <img class="imagen2" src="imagenes/imagen2.jpg"/> </body> </html> With the file for example called styles.css for example in a directory in the root called css, for the route to be indicated: css/estilos.cssAnd in its content:.imagen1{ width:50px; height:50px; } .imagen2{ width:60px; height:60px; } Is CLASS equal to ID?You have been able to observe that CLASS is identified in the style sheet with a point. You can do the same with ID but then instead of a point you should use a #. You'll work the same way. What's the difference? ID should be used for a single element, and CLASS can use it for more than one element you want to give the same style or features. If you have any doubts, you'll tell me.Greetings and enjoy!

The size of struct it's not possible. What seems to be wanting is to increase the size of array. It doesn't give dynamically, it's that size.What you can do is allocate in heap a portion of enough bytes to store the amount of objects you want ( http://en.cppreference.com/w/cpp/memory/c/malloc ) and if it reaches the realocar limit ( http://en.cppreference.com/w/cpp/memory/c/malloc ). This way you will have a pointer generated by the allocation function creating an indirection.I've answered something about https://pt.stackoverflow.com/q/41692/101 , https://pt.stackoverflow.com/q/52555/101 and https://pt.stackoverflow.com/q/132158/101 . It can also be useful: https://pt.stackoverflow.com/q/40562/101 It can be useful: https://pt.stackoverflow.com/q/106719/101 . A question has already been asked about allocation: https://pt.stackoverflow.com/q/43766/101 .And there's nothing wrong with the statement of struct.

If this <select> is being mounted dynamically and you want to add more items "dynamically", you must seek the element dynamically:let categorias = [ { id: 001, value: 'imoveis' }, { id: 002, value: 'carros' }, { id: 003, value: 'celulares' }, { id: 004, value: 'computadores' } ] // primeira iteração (adicionar categoria(s)) categorias.forEach(item => { $('#select').append(<optgroup id="${item.id}" label="${item.value}"></optgroup>) }) // segunda iteração (adicionar itens a elementos dinamicos) categorias.forEach(item => { $('#'+item.id).append( <option>item 001</option> <option>item 002</option> <option>item 003</option> ) }) <script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script> <select id="select"></select>If you know the data structure you should simply map it and iterate. This data can come from a JSON ai just make the parse (JSON.parse()) if it is a matrix already available on the front end (javascript) it is enough to run through it.This example is simple and distributes in groups, even if your solution uses a select "customized" logic should be the same.

(1) If string contains only Latin letters or symbols in 8-bit encryption (Win1251, for example), please refer to the i-word as str[i].(2) If string contains the letters of the national alphabet, it is UTF-8 and one letter may be from one to four byte. It is not possible to define the letter ' s position without a complete breakdown of the row (through Unicode code points) so that the only reasonable way would be to convert the row into UTF-16, after which symbols can be used as (1). For example:string str = u8"Шаланды полные кефали"; std::wstring_convert<std::codecvt_utf8<wchar_t>> conv; wstring wstr = conv.from_bytes(str); wchar_t ltr = wstr[2]; // Cyrillic letter 'л'

What I could do is to iterate for every element that has the class .destinoDato and pass the value of the keyup event in this way: $(document).ready(function(){ var i=0; $(".origenDato").keyup(function () { let valor_a_pasar=$(this).val(); $('.destinoDato').each(function(){ $(this).val(valor_a_pasar); }); }); $('#CantidadTeo-' + i).change(function(){ upd_art(i) }); $('#CantidadFab-'+ i).change(function(){ upd_art(i) }); $('#add').click(function(){ i++; }); });

Most of the answers to these questions are in the documentation.As an extension of the ANSI/ISO SQL92 MySQL, it is possible to indicate, if necessary, the number of symbols supplied to the user of the whole number. This non-mandatory indication of the number of deleted symbols is used to supplement the left-hand values that contain symbols less than the specified width of the column, but does not limit either the range of values that can be stored in the column or the number of discharges that can be derived for values where the number of symbols exceeds the width of the column. If the non-mandatory ZEROFILL attribute is added, the free default positions are filled with zeros. For example, for a column declared as INT(5) ZEROFILL, value 4 is recovered as 00004. It should be borne in mind that if the whole cell column contains a value with a number of symbols exceeding the intended width of the column, there may be problems when MySQL generates time tables for some complex connections, as in such cases MySQL believes that the data were indeed a pole of the existing width. http://phpclub.ru/mysql/doc/numeric-types.html

I've come to an option, such as a critical issue. The option is to create a set of generators, each of which will work for its flow. Yeah, for every target there's gonna be a separate set of generators. Code:__global__ void initGen(thrust::uniform_real_distribution<float>* dist, thrust::minstd_rand rgn, time_t seed) // seed - берется извне из time(0) { int index = threadIdx.x + blockIdx.x * blockDim.x; rgn[index] = thrust::minstd_rand(seed + index * 10000); //index добавляется для различий в сидах разных потоков\генераторов. gen[index] = thrust::uniform_real_distribution<float> dist(-10,10); } global void doGen(float* a, thrust::uniform_real_distribution<float>* dist, thrust::minstd_rand rgn) { int index = threadIdx.x + blockIdx.x * blockDim.x; a[index] = (*dist)(gen[index]); } int main() { // инициализация devA на девайсе // ... thrust::minstd_rand devRgn; cudaMalloc((void*)&devRgn, sizeof(thrust::minstd_rand) * size); // size -> of array // аналогично для uniform_real_distribution int seedTime = time(0); initGen<<<blocks, threads>>>(devDist, devRgen, seed); for(/loop/){ doGen<<<blocks, threads>>>(devA, devDist, devRgen); // ... do smth with devA } // ... // free/cudaFree } In fact, all the generators are recorded on the motto (if not, they're built and lived only there) and occupied there. As rational as it is to use memory, I don't know, sizeof(s) writes 4 and 8 for minstd_rand and uniform_real_distribution, respectively. It's like three extras. float/int One object. We'll see how realistic it is.
