I see that variations on this question have appeared before but I'm still completely stumped.
I'm developing an application with a fairly robust graphics component for 3D rendering. I've written all the 3D rendering scripts, but what's really hanging me up is how to I pass information from an one-dimensional arraylist to a two-dimensional array. Here's what I'm trying to do:
1) My program generates an arraylist called "mpoints" of 2D...

I used to work with C and have a set of libraries which allocate
multi-dimensional arrays(2 and 3) with single malloc call.
data_type **myarray
= (data_type**)malloc(widht*height*sizeof(data_type)+ height*
sizeof(data_type*));
//allocate individual addresses for row pointers.
Now that I am moving to C++,am looking for something by which I can

I have multi-dimesional arrays that can be specifed by the user, e.g
1,2,3,4,5
1,2,3,4,5,6,7,8,9,10
1,2,3,4,5,6
I think a bit of code that will iterate over these arrays to print out
the element indices for each unique element in the N-dimensional
array. E.g. for the above

Hi,
Why does gcc (3.3.2) give me a 'initialization from incompatible pointer

All this time I was under the illusion that I understand the concept of
multi-dimensional arrays well ---- however the following code snippet
belies my understanding.
I had assumed all along that a declaration like:
int intArray
means that there is an array of pointers to int with a size of 5, each
of whose elements is an array of int with a size of 3.
This definition seemed intuitive to me since a declaration like

I am trying to pass a slice from a larger 2-dimensional array to a
function that will work on a smaller region of the array space. The
code below is a distillation of what I am trying to accomplish.
// - - - - - - - - begin code - - - - - - -
typedef int sm_t;
typedef int bg_t;
sm_t sm;

I can easily store a one-dimensional array in viewstate ( see Test1 )
If I try storing a multi-dimensional array in the viewstate it's crapping
out on me when it goes to serialize the array (not when I make the
assignment).
Interestingly, I get a very different error depending on the type of array
( string or decimal ).
I'm not doing anything fancy, just a regular old aspx page with a single

Hi, I have two questions:
1.)Is it true that an rectangular array is really just an single
dimensional array that lets itself be treated as a multi-dimensional
array?
For example the following declaration:

Hi,
consider the attached code.
Serializing the multi-dimensional array takes about 36s
vs. 0.36s for the single-dimensional array.
Initializing the multi-dimensional array takes about 4s
vs. 0.3s for the single-dimensional array.
(I know initializing is not necessary in this simple example,

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:

Dear forum friends,
With the development of smart home technology, a variety of wireless communication protocols have appeared on the market, such as Zigbee, Z-Wave, Wi-Fi, Bluetooth, etc. Each protocol has its own unique characteristics and advantages, but as a user who is planning to build a smart home system, I am a bit confused by the choice of these technologies. I'm particularly interested in Zigbee because I've heard it does some...

Let's talk about the concept of autonomous AI software engineers and no-code agents.

Imagine an AI that can take a project description, break it down, write the code, debug it, and then launch it, all on its own....
