Initiation of the indicator C

I'm interested in your review of the table of this resource. http://microsin.net/programming/dsp/difference-between-pointer-and-array-in-c.html in paragraph 2 of the comparison table
1. The indicator cannot be initialized in the definition. Nor can it be possible to initiate the memory indicated by the index when defining the indicator.
What does that mean?
I can give the address to the teller in clear form.
```
char* prt = (char*) 0xB8000000;
```
The index in this code indicates the area of memory 0xB8000000. I understand the statement, "The Denominator cannot be initialized in the definition." That's not correct.
Is the author wrong?

The author of the article is wrong.
He seems to mean that one line cannot create a dynamic body and immediately indicate its elements.

At least add CMakeLists.txt:target_link_libraries ( bufr_drawer ${PYTHON_LIBRARIES} ) include_directories ( ${PYTHON_INCLUDE_DIRS} ) But that's how you're just gonna get a complete file to use a piton... To collect a piton module from which C-code can be called requires something else. ♪ ♪

You need a field like this. fixed♪ Unfortunately, such fields can only be single-dimensional, so you're gonna need an accessory for the double index:[StructLayout(LayoutKind.Explicit)] unsafe struct AVPanScan { [FieldOffset(0)] public Int32 id; [FieldOffset(4)] public Int32 width; [FieldOffset(8)] public Int32 height; [FieldOffset(12)] private fixed Int16 flatPosition[6]; public Int16 GetPosition(int i, int j) { return flatPosition[i * 2 + j]; } public void SetPosition(int i, int j, Int16 value) { flatPosition[i * 2 + j] = value; } } (In C# there are no named indices, so two methods have to be used.)Right.

Are you running in the terminal? If you are, you can save what would be your entry into a text file and take the test by redirecting the input. Supposing the file with the data is named entrance. tx, you can perform as follows. C:\Users\usuario> nome_programa.exe < entrada.txt Or, you can redirect the input into the code itself with the freopen function (only to test). The example below shows how I did to use as input of my program the data that were in the name file in. If your file is in the same directory there is no need to place the complete path. freopen("C:/Users/slipn/Desktop/in", "r", stdin);

You have some wrong things in that code:You have to initialize the map of characters before using it;You cannot assign a string to a character;char map[][1] = "gabriel";Code:#include <stdio.h> #include <stdlib.h> #define N 10 int changeMap(char mp[N][N], int x, int y) { mp[x-1][y-1] = 'X'; return 0; } int main() { char map[N][N]; //inicialização do map de N por N map[0][0]= 'T'; //atribuição do 'T' a posição x=0, y=0 printf("%c", map[0][0]); changeMap(map, 1, 1); printf("%c", map[0][0]); return 0; } Result:TX http://ideone.com/MIrPt9

Does it make sense to store a pointer to the next location?The truth is, no. Not only because data are already in consecutive memory positions, but other factors need to be taken into account:If a registration is removed, an indeterminate number of pointers must be recalculated.If a registration is inserted, an indeterminate number of pointers must be recalculated.If the pointers force leaps in the file (registration 1 points as follows to record 45) the location of the data is broken and that forces the system to regroup the cache, which has a very negative impact on performanceIf something goes wrong, can be caused by circular lists or we can have orphan records (there are but no one links them as follows).So... how could it be done?As a general rule, the simplest is usually the best way to start. Suppose, based on the data of your question, we have such a structure that:struct Datos { char nombre[50]; char apellidos[100]; int edad; }; If the data is saved in binary format it is normal for each record to occupy 154 bytes (in some platforms you can occupy 152), but it will always be sizeof(struct Datos). If we assume that the size is finally 154 bytes the records will be stored in the file as follows:offset 0: first recordoffset 154: second recordoffset 308: third record...If we do not store an insulting amount of data, sequential reading is the best solution: easy to implement and with relatively short access times. A search example:while(1) { struct Datos temp; fread(&temp,sizeof(struct Datos),1,fich); if( feof(fich) ) { // Final del fichero } else if( strcmp(temp.nombre,"pepito") ) { // Tenemos el registro buscado } // ... } Sequential search has as inconvenconvenience that with a large volume of data, locating an element that is at the end of the file may require quite some time... The solution in these cases is usually the same as that applied in database engines and consists in creating indexes. The structure, design and number of indices will depend on the requirements to be applied in searches, but a simple example could be to have a second file in which the indices of the records are stored, sorted by name. A practical example:data.txtNOMBRE roberto pedro valentín sergio indice_name.ind1 0 3 2 Now you could apply search algorithms on the index. For example... if for example the name begins z you could go through the index inverse sense to find the record without having to go through the entire file.Does it make sense to have the log divided into several files?If we look back at the database design we find that, at times, it is necessary to access several tables to recover all the information regarding something.These tables often express some kind of relationship between the data (e.g., a person may have 0 or more cars to his name. This relationship would be complicated to manage with a single file).The topic of databases in general and of databases in particular would give for a thousand responses such as these, or more. The Internet is overflowing with books and documentation, so it would be interesting that, if the subject is attractive, you start browsing for all that documentation.What if we have the data in memory?Memory is much faster than files. If it is possible to bring the data to the memory we will achieve a huge reduction in the times of consultation. In fact, the graphics engines usually have a series of cacheados records with the idea of not having to go to the files to recover that information.On the other hand, it should be borne in mind that memory is not a persistent system. If you leave the light or close the application the contents of the memory will be lost. It is therefore important not to lose sight of the fact that the data should be taken at a certain time to a persistent device (such as a file) to avoid loss of information.

The month if the user is not going to insert the user, you want the program to get it, then you should include the following:#include <time.h> And in your code to declare the variable month do the followingtime_t ahora; //Obtiene la fecha actual del sistema time(&ahora); //Se convierte a una estructura tipo calendario para poder obtener todas las variables struct tm *local = localtime(&ahora); //Seleccionamos el mes de la estructura y tm_mon nos devuelve un número entre 0 y 11 por lo tanto le sumamos 1 int mes = local->tm_mon +1; This code I got from this website, which is in English I don't know if it's helpful for other things related to the date. https://www.techiedelight.com/print-current-date-and-time-in-c/ I hope it's help.

Example in the code is a classic example of the difference between c and c+++. In s++, the symbol is char. And the size of it is 1. All are given int and size 4.And the difference between single and double rubbers is just a single symbol, a double line (massiv char).The most interesting thing about it is. https://ru.wikipedia.org/wiki/%D0%A1%D0%B8_(%D1%8F%D0%B7%D1%8B%D0%BA_%D0%BF%D1%80%D0%BE%D0%B3%D1%80%D0%B0%D0%BC%D0%BC%D0%B8%D1%80%D0%BE%D0%B2%D0%B0%D0%BD%D0%B8%D1%8F)#%D0%A1%D0%B8_%D0%B8_C++ It says:And read it. http://alenacpp.blogspot.com/2009/03/sizeofa.html ♪

There's a way to use it. \r and take a new line up the old one. look. numerals will be as unchanged...) or (this is not appropriate for you)Use "baby" to the right number of symbols and only change the numbers.I would record everything in the line I kept. Then I'd compare two lines and watch where the difference begins.With the keys, if you have the same in the system. <conio.h>, check in the same cycle, see if the keyboard was pressed, and if it was, which one. ♪ ♪

Depends on, as they say. Imagine that you're returning the index to some static body or something, a word, a memory that should be removed. Turning him into an intellectual index doesn't make much sense. ♪Or, let's say, you've prepared a line to remember and decided to return it as an index. Then it makes more sense to get her back. string♪In the words, the only right solution does not exist and cannot exist. There is always a specific task, not abstract submissions:But it is understandable that if it is to restore the dynamic memory that must not be forgotten, then yes, it is better to use the intellectual index.

The headline doesn't have to be 54 bayth, it can change. You'd better figure out where the peaks are starting from the field. bfOffBitsheight * width * 3 - The wrong formula.

The author meant in the second part of the statement the following.If you have the following announcementsint x; const int cx; int *p; You can write.p = &x; But you can't writep = &cx; It's not about the tip of the index itself. It's just that there's a bad translation that the index to the non-constant data is called a non-constant index.With your exampleint a = 5; int * const ptr = &a; If you're strict, there's no embezzlement. There's an initialization of the terminal facility. And if you're going to use a real attribution, the compiler will give a misstatement.For example,int a = 5; int * const ptr; ptr = &a; This fragment of the code will not be compiled because the stop index should be initialized when an announcement is made and, moreover, it cannot be assigned value.
