Hi everybody
The output of my multiple dimension array is quite confusing.
Im declaring an array, store some values in it and then I save the array
in a session variable. On an other page I store the data of the
session in a new multiple dimension array.
All data are saved correctly in the array of the 1st page. But in the
new array of the 2nd page there is only one entry. Does anybody knows

Hi,
I am new to C++. I want to directly create a dynamic two-dimension
double array, i.e. double pp. I found the "new" is only for
one-dimension array, i.e. double *p = new p. How to
"new" a two-dimension array?
Is the only way to create a class?
In java, I can easily create a two-dimension array by "double pp =
new double". But, how to do it in C++?

The input to a function of a 3rd party library I want to use requires a
double**, which is a multi-dimension array of doubles.
I have looked on the net etc and seen several ways of supposedly doing
this, but I don't seem to be able to get them to work. I was wondering
if anybody can tell me what I am doing wrong.
int rows = 10 ;
int cols = 10 ;

Hi,
I'm using VC++ 7.0 (VS 2003).
My code:
void main() {
int *a = new int;
}
I'm sure that the above code is accepted by VC++ (no compiling error).
What is exactly the semantic of the above code ?
Is is an implicit conversion from multi-dimension array to 1-dimension array
? If yes, what is it usage ?

Hi, All
I have a conventional question, How to create a 3 dimension array by C
language.
I see some declare like this:

How can I sort a two-dimension array on the first dimension in the array?
If there's not a way to do it, how can I return the values of the first
dimension so that I can sort the values myself (bubble sort, etc.)?
Thank you

This code snippet is an exercise on allocating two dimension array
dynamically. Though this one is trivial, is it a correct one?
Furthermore, when I tried to make these changes to the original
example:
for (i = 0; i < ROW + 2; ++i){ /*line 14*/
strcpy(array, "C! C!"); /*line 15*/
Apparently, the modified code wrote to the memory unit outside the
allocated array, but the program ran well and there was no Segmentation

Is it always legal to cast expressions of type of multi-dimension
array to type of pointer?
Including:
T to T* ,

T to T* ,
and so on...
For example:

What code do I use to find the lowest and the highest value in a two dimension array. I have written the code to have a user enter values into the array, as well as getting a total and average of all values in the array. This is the last part of an assignment due on 04/22/2010.
Thank you!

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...
