  1. Some question in memory [ Data Structure ]

    what do you mean by standard since 2011 ?
  2. Some question in memory [ Data Structure ]

    For the same code : class B{ public: int age; int code; B(){ cout << "Age | " << &age << endl; cout << "Code | " << &code << endl; } }; int main() { B obj; cout << "Object | " << &obj << endl; return 0; } Output : Object | 0x6afef8 this object is just a pointer right ? how this pointer points to all the member classes ? how to get the offsets of the class member ?
  3. Some question in memory [ Data Structure ]

    Suppose i have this code : class B{ public: int age; int code; B(){ cout << "Age | " << &age << endl; cout << "Code | " << &code << endl; } }; int main() { B obj; cout << "Object | " << &obj << endl; return 0; } Output : Age | 0x6afef8 Code | 0x6afefc Object | 0x6afef8 here why the object address is the same for the age address ?
  4. Some question in memory [ Data Structure ]

    So if i have 2 boxes one for x and the second one for *ptrx Say that the box of x is in location 0x1000 and the ptrx is in the location 0x2000 int x = 15; int *ptrx; now if i made this ptr points to x how the boxes will be at the same location ???! for example how we will have a box of x in the location 0x1000 and the box of pts in the location 0x1000
  5. Some question in memory [ Data Structure ]

    So if i have a class of 2 attributes class A{ int age = 15,code = 30; } new A(); now this code allocates 12 bytes in memory for the object which for example : say that the address of the object is 0x100 so the age will be at 0x104 and the code will be at 0x108 (4 bytes (int) ) is that right ? now when i do that A obj = new A(); obj is a pointer which points to the object and the age and the code is that right and i really wanted any videos about that to understand better because i stopped coding just to understand how things work
  6. Some question in memory [ Data Structure ]

    so when i say x = y that means the value of y equals x not means the address of y = x right ? in java there's no pointers linke the * in c++ so how for example can i make the address of x equals the address of y and what about the objects
  7. Hi i am actually having some problems in understand what happens in the memory ... for example i have 2 int variables [ int x and y ] x = 15 and y = 30 in memory for example the address of x = 0x123456 and the address of y = 0x654321 now if i did this x = y isn't that means in memory the address of y will be the same for x or what ---------------------------------------------------------------------------------------------------------------------------------------------------------------------- Now here in java in creating objects ... say that i have a class called a and the attributes is name and age so when i create an object : a objectreference = new a(); now i have allocated the memory for the object of class a and a reference called objectrefernece reference to object of class a now how this objectreference reference to the object ? how that's done in memory also what happens in memory when i create an object and what happen to the attributes i wish if u can answer me
  8. Question about C++ , C# and Java

    You guys didn't actually get what i meant i see that people says that c++/cli is not the same for c++ like gcnew , ^ pointer etc ... And they says mfc or qt is better i have already used both of them mfc and qt but i didnt like both of them so i can continue on using clr ?
  9. Hi i really wanted to know if i am in the right section or not to ask this question how ever ... I have already learned the basics of C++ and C++/CLI i have learned C++ for building gui for desktop applications and now i am just learning the basics of java nothing more just to use Android studio to build android apps how ever now i am having some problems with the desktop applications for building gui ... which is the best and faster language C++ / C# or java ? I am currently using C++/CLi (Clr) in C++ but i see many peoples says that Qt is better i have already used Qt but i didn't like Qt and i like clr much more and i also see that many people says that for building gui C# is the best choice while the others says that C++ is faster than C# so what is the best way i have to choose ... Do i have to complete in learning C++/CLi and continue bulding gui apps in it or i have to learn C# or i have to use Qt answer me please
  10. C++ Getting unicode from an ini file

    Becouse i am using C++/CLR so gcnew is like new and ^ is like * and String is like string
  11. Hi, i wish if everyone is having a good day My question is about I am reading the selected text from the listview String ^ItemSelected = listView1->SelectedItems[0]->Text; But i wanted to write the result to an ini file but since the Writeprivateprofilesection needs an parameter of type LPCWSTR i cannot pass ItemSelected to it WritePrivateProfileSection(ItemSelected,L"Key = Value", L".//Text.txt");
  12. C++ Getting unicode from an ini file

    Okay guys the problem was that the ini file was UTF-8 and not unicode hhhhhhhh Anway i wanted to ask another question ... Since the Get and buffer are not char and TCHAR So when i use MessageBox::Show(Get); It will give me error so i have tried this : String ^GetResult = gcnew String(Get); MessageBox::Show(GetResult); This one works but i don't know how this line works String ^GetResult = gcnew String(Get); Can you please explain it ?
  13. Hi, this is my first post here and i hope to get an answer My question is i am reading the section names from an file Unfortunately these section name contains unicode chars so when i read them i just get ???? here's my code ... TCHAR buffer[4096]; int Lsize = sizeof(buffer),length; GetPrivateProfileSectionNames(buffer,Lsize,".//Test.txt"); TCHAR *Get = buffer; while (*Get){ length = strlen(Get); Get += length; Get++; }
