Nothing would help, my son and exgf are here hence I am geographically bound

Hi.. Did someone have experience with R Shiny dashboard ?

He's asking about settings, not about bus attachements?

It doesn't have stack allocation of objects

in C object are structure and you can allocate in stack. In C++ are class, a special type of structure.

int a = 10; int a(10); int a{10}; Which declaration type have less runtime complexity..? Means less space complexity and time complexity..

On a local scope? Thats put in a stack-frame?

{ struct abc a; } If struct abc is big it's allocate on stack, otherwise in register

{ struct abc a; } If struct abc is big it's allocate on stack, otherwise in register

{ struct abc a; } If struct abc is big it's allocate on stack, otherwise in register

Yes, but if you declare an object in C# it declares on the stack a pointer to that object, never the object itself

In register if its small enough and if your compiler is smart enough and can cope with that

Object in C is a instance of structure. Object in C++ is a instance of classe. C and C++ are two different language with different meaning of object

Do you know why CPP was ever incepted?

The meaning in C is completely valid in C++

struct abc{ int v; }; struct abc foo(void){ struct abc a= {.v=1}; return a; }

This is valid C++

struct abc{ int v; }; struct abc foo(void){ struct abc a= {.v=1}; return a; }

int* a = malloc(sizeof(int));

This is not valid C++ but have nothing to do with objects

sizeof('a') != sizeof('a')

This is valid C++

?

sizeof return different size between C and C++

Not for primitive types

struct abc{ int v; }; struct abc foo(void){ struct abc a= {.v=1}; return a; }

sizeof(char) is 1 in both C and C++ C++ 8.3.3 C 6.5.3.4

'a' is primitive?

Yes, and those sizeof return both 1

But not sizeof('a')

sizeof(char) is 1 in both C and C++ C++ 8.3.3 C 6.5.3.4

the only type that is standardized 😢

no, int and float and standardized as well. the size is not

Actually C and C++ may actually not even use bytes of 8bits

Because in C it is undefined behaviour

C++>1.0 is not a superset of C, C++ 1.0 is

Yes!

Well.. somewhat
