Type casting from one namespace to the other.

Hi All,

(I first posted this question on the csharp.general but got no response, and
since this NG is more active, so I repost it here)

I have two enum definitions from two different namespaces:

namespace ns1
{
public enum e1{

e1a, e1b ......

}

}

namespace ns2
{
public enum e2{

e1a, e1b,... e2a, e2b ...... (i.e. e2 extends the e1's enum)

}

}

Let say in ns1 I have created a array such that

e1[] e1Array=new e1[10];

If I passed the e1Array into a routine, is it possible to cast it into an n2
array, e.g.

e2 e2Array = (e1[]) e1Array. <--- not working.

Anyway get do this?

TIA.

Hi,
I think that you can't make a cast to enums
you should try to play with the numbers values of the enums, remember
that the elements of enums are internaly numbers

Thanks, Horacio.

Actually I was trying to do something like:

// bassically a switch wrapper

e1[] getSet()

{

if (wante1) // set somewhere

return getSetFrome1();

else

return getSetFrome2(); <--- that is my problem if I want to return the e2
array

in e1 namespace, could the cast be used?

}

Namespace e1ns

{

Public e1[] getSetFrome1()

{

Return new e1[x];

}

}

Namespace e2ns

{

Public e2[] getSetFrome2()

{

Return new e2[y];

}

}

I have a c struct from old code that cannot be modified and I am trying to write a wrapper C++ class around it. This class is often passed as a pointer to some c functions of a library and I wanted to keep my new class transparent and compatible with those functions. That is, when using the code, I should be able to do either: oldVector xyz; function( &xyz ); myVector xyz; function( &xyz );

** Isn't the 'static_cast' operator the same as traditional type casting? ie, Aren't the following ways of getting b1, b2 the same? // 'Derived' is derived from 'Base' Derived* d = new Derived(); Base* b1 = static_cast<Base*>(d); Base* b2 = (Base*)d; // traditional type casting Such is my understanding from code samples, my own uses, and this: http://www.cplusplus.com/doc/tutorial/tut5-4.html

Hello folks, I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>". The problem is that using the GNU compilers, it seems that the internal comparison operator "<=>" tries to promote arguments from unsigned to signed. This is as boiled down as I can make it. Here is my compilation command: g++-12 -std=c++20 -Wnarrowing bit_field.cpp Here is the code in...
