Hello, please a little question, in Microsoft examples initializing IWbemLocator* pLoc = NULL; or also IWbemLocator *pLoc = 0; why do not use nullptr to inizialize the pointers?

Because api is made for C

then nullptr is interpreted differently ?

There's no nullptr in C

Isnt a nullptr just (void*)0 ?

I don't think so

It is NULL in C.

i have something like, union A { struct{ int i; } ; struct{ int j; }; } ; A *ptr = nullptr; if i want to achieve ptr->j. how to do it?

i have something like, union A { struct{ int i; } ; struct{ int j; }; } ; A *ptr = nullptr; if i want to achieve ptr->j. how to do it?

i have something like, union A { struct{ int i; } ; struct{ int j; }; } ; A *ptr = nullptr; if i want to achieve ptr->j. how to do it?

NULL in C++ is 0, so I thought that might be it. A zero casted to a void pointer

NULL in C++ is nullptr.

NULL in C++ is nullptr.

struct A{ int i; } ; struct B{ int j; } ; std::variant<A, B> *ptr; now if i want ptr to have j as a member then how to do it? ptr = new B(); gives error

Why do you even use ptrs?

NULL is 0, nullptr is nullptr.

NULL is ((void*)0) in C but in C++ you should use nullptr because it's C++ not C

Hlo anyone can send me all header files of c++ Window 10

Can you guys please suggest me a good and easy to use IDE for C & C++ as a beginner?

Someone please reply!

Or use visual studio.

VS Codium / atom

Here are some cool text editors: Atom VScode Notepad++ / Notepadqq Emacs or VIM if you want to invest some time learning them And some IDEs: Geany Netbeans Eclipse The intelliJ IDEs, some of them are paid only tho

You really use xterm?

I cant see a thing with xterm

All my terminal does is clear ; make ;make clean 😂

I love makefiles. Visualstudio does everything for you, makes spoiled progammers :(

It is easily configurable with Xresources, you even can use xft fonts. So it’s not hard to make it look nice

you just need to add some good fonts and colors

I suggest you to write comments in English even if it isn’t your native language

yes, and the footprint is really small

+ plus it’s part of base system distribution of X, but it’s all off topic, sorry for that

Makefiles could be considered traditional only for Unix like systems I think. Also makefiles is almost turing complete, but still not portable to systems with different shells. You can find build systems with more reliable syntax and then cross platform, like meson

Sry sry I didn't see it someone had send a msg that his mood was damn fucking and I replied u instead of someone else

#include<iostream> using namespace std; class Employee; class clerk { public: void print(Employee); }; class Employee { string name,gender,dep; int empid,age,sal; public: friend void clerk::print(Employee); void read() { cout<<"\n enter name "; cin>>name; cout<<"\n enter empid "; cin>> empid; cout<<"\n enter age"; cin>>age; cout<<"\n enter gender "; cin>>gender; cout<<"\n enter salary "; cin>>sal; cout<<"\n enter department"; cin>>dep; } void show() { cout<<"\n the information of employee is:"; cout<<"\n name "<<name; cout<<"\n empid "<<empid; cout<<"\n age"<<age; cout<<"\n gender"<<gender; cout<<"\n salary"<<sal; cout<<"\n department"<<dep; } Employee() { cout<< "\n default constructer called"; } ~Employee() { cout<<"\n destructor called"; } }; void clerk::print(Employee emp) { cout<<"\n name "<<emp.name; cout<<"\n age "<<emp.age; cout<<"\n gender "<<emp.gender; cout<<"\n salary "<<emp.sal; cout<<"\n department "<<emp.dep; } int main() { Employee emp; emp.read(); clerk cl; cl.print(emp); }

Plz can explain further to me
