Hi,
If I want to call functions that don't return int without declaring
them, will there be any harm?
I only want to assign the function(return value) to the type that it
returns, so I don't see how the return value comes to play here.

Good afternoon,
I am creating an interface in C++ using the managed extensions. I need to
declare a parameter as an out string (as would be represented in C#). Does
anyone know how to do this? Declaring out parameters generally takes the
form:
<type> __gc* name
and arrays generally take the form:

When I declare an array as double(,) then try to use it I get an error:
"Object reference not set to an instance of an object."
I have found that I can redim the array and all is well. Is my approach
proper here or is the a better way for setting the instance of this specific
format for an array.

Hello,
I am using Visual Web Developer 2005 Express. I want to declare a varible,
using Visual Basic as the language and can't get anywhere. For example

Hello,
I'm having some difficulty compiling template classes as containers for
other template objects. Specifically, I have a hierarchy of template
classes that contain each other. Template class B has an instance of
template class A, which has some base type T (usually int or double).
However, the base type T is important to calculations in B, so I would
like to obtain access to the type for further variable declaration
within B. ...

There is already one function processing pointer values this way. And
there may easily appear more, including wrappers for this function.
For purposes of further discussion, consider simplified function,
`consume'. It has one arg, INBUF, that points to a variable that
points to the first character in the input buffer. The function never
modifies characters pointed to by `*INBUF'. It, however, updates
the `*INBUF' value to point to...

Hello,
Is there a simple way to resolve declaring class of a method at runtime ?
Consider this simple example:
$ python
Python 2.5.1 (r251:54863, May 18 2007, 16:56:43)
on cygwin
Type "help", "copyright", "credits" or "license" for more information.

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...
