struct matrix_array{
float **sy,*sxx;

newdata ndata;//new data struct
ndata.sy=matrix(1,nvar,1,nstep);

The c# code style guide that I follow suggests that class variables (fields)
be coded with camel casing, like this:
int recordId;
string name;
It also suggests that variables within methods and method parameters use
camel casing, like this:
void SetName(int id, string newName)

emmm, this is taken from the exam I just finished this morning:
Which one is correct:
A) double *ptr = (double *) malloc(100 * sizeof(double));
B) double *ptr = (double *) malloc(100 * sizeof(double *));
C) double ptr = (double) malloc(100 * size0f(double));
D) double *ptr = (double) malloc(100*sizeof(double));
My choice is A.

Hi All ,
As a process of my C language learning I was trying to learn how
malloc can be implemented from K&R2 .But I am not able to
understand few points . It would be very much helpful if some body
give some inputs in the bellow mentioned points.
Point 1) I page 186 it is said that "In malloc, the requested size in
characters is rounded up to the proper number of header-sized
units; the block that will be allocated contains one...

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,...
