Question is about the difference between these two
reference to an object versus pointer to an object
What are advantages in either one and when would one use them. I see
lots of examples when an object is passed as a parameter to a function
it is passed as a reference. Though it would have been fine to pass it
as a pointer as well ? is that right ?
I had posted a similar question in the C lang newsgroup but did not
get much help as C...

Hi. I'm more-or-less a C newbie. I thought I had pointers under control until
I started goofing around with this:

/* A function that returns a pointer-of-arrays to the calling function. */
#include <stdio.h>
int *pfunc(void);

Hi,
I've got a program whose main object contains an array of "cells", each
of which contains an array of "sub-cells", each of which contains an array
of "sub-sub-cells". The cells, subcells and subsubcells are three
user-defined types, each of which contains some program logic as well as
some drawing capabilities. Since all cells (and subcells and subsubcells)
will utilize identical drawing "settings", I'm using a single settings...

I have problem understanding pass by value and pass by reference and
want to how how they are or appear in the memory:
I had to get my basics right again. I create an array and try all
possible ways of passing an array. In the following code, fun1(int
a1) - same as fun1(int* a1) - where both are of the type passed by
reference. Inside this function, another pointer a1 is created whose
address &a1 is different from that of the passed...

Deal all,
The type
typedef double ***tmp_tensor3;
is meant to represent a three-dimensional array. For some reasons the
standard array-of-array-of-array will not work in my case.
Can I convert an object of this type to the following type?

Why would a method that is defined to return a reference such as with the
operator overload of , operator,
href& operator(int index){
return _array;
}
not cause a type mismatch compiler error?

Overview:
Windows 11 and 10 have less user interface control over operating system update behaviour than previous versions of Windows. In Windows 11 and 10, there is no way to turn off the Windows Update option using the Control Panel or Settings app; it automatically checks for updates and installs any it finds, whether you like it or not. For most users, this new feature is actually very convenient. If you want to control the update process,...
