Hi,
I am just learning about the array/pointer duality in C/C++. I couldn't
help wondering, is there a way to pass an array by value? It seems like
the only way to do is to pass it by reference??
Thanks,
BB

Hi!
I've been thinking about passing parameteras using references instead
of pointers in order to emphasize that the parameter must be an
object.
Exemple:

Hi all,
I am new to this group and I have question that you may be able to
help me with.
I am trying to learn C but am currently stuck on this.
First of all, I have a function for each sort (Bubble, insertion,
selection..).
I have an array of int's and am passing them to each sort function.

I know this is somewhat dependent on the circumstances, but let me ask
anyway. Suppose I have a 100 byte struct or array or something like
that. Which would be more efficient?
void function(struct something foo)
{
foo.this + foo.that;
foo.somethingoranother++;
printf(foo.foostring);
//other operations on the array

Hello All,
I am relatively new to C programming and I am struck with a problem in
dynamic memory allocation.
I would like to know if it is ok to pass the 'memory address' returned
by malloc()(stored not in a pointer variable but as an element of an
array of type int*) directly to free(). My program allocating and
freeing memory this way is corrupting the heap.
Can anybody guide me on this.
Thanks in advance

When try pass only one delegate as parameter, all work fine.
But I need call function, that take as parameter array of function
pointers. From C++ code I used such code:
static void* aFuncPtrs =
{
&Function1,
&Function2,
&Function3,
};

I wrote a function foo(int arr) and its prototype
is declared as foo(int arr); I modify the values of the array in the
function and the values are getting modified in the main array which
is passed also. I understand that this way of passing the array is by
value and if the prototype is declared as foo(int *), it is by
reference in which case the value if modified in the function will get
reflected in the main function as well. I dont...

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...

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...

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,...
