I'm a novice with c/c++ and have been reading Eckel's book. I'd like
some feedback on using this method. What I need to do is treat a
string as numeric data. I know how to write functions to convert
between data types, but was thinking that this isn't really necessary
since I can access the memory directly in c. I want to treat the text
as native integer so that I can perform fast bit-level manipulations.
This code works fine...but I'm...

I have a char array and when I write it to a file using BinaryWriter the
position of the pointer is the size of the array + 1. For example: writing
char leaves the pointer at position 26 after starting at position 0. I
thought that char was 2 bytes, but this makes it seem as though it is just 1
when I write to a file. Why is this? I imagine the extra bit is just a null
bit (correct me if I'm wrong). I don't know if this helps but when I...

Hi there!
I've been having a lot of difficult trying to figure out a way to convert
a terminated char array to a system::string for use in Visual C++ .NET
2003.
This is necessary because I have some legcay C code that needs to process
a string taken from a textbox, then I need to re-display the string as the
textbox->Text. I easily found how to convert from system::string to char
but I can't figure out how to go the other way!!

hi,
wrote the following program to learn a bit about auto pointers.
weird thing is, the char array 'name' with size 'max_size' displays a
bunch of messed up symbols after the "John Smith" if max_size is larger
than 28. why is that? I found this out by playing with max_size after
I couldn't figure out what I did wrong.
thx a bunch

How do I copy the content of a string in one encoding (in my case big5) to a
char array of the same encoding?
I try the following
String line = S"123æ°´æ³¥";

Hello.
I have the following code, to do a simple operation by copying the elements
of a vector of strings into an array of char pointers. However, when I run
this code, the first element in the char array strarr holds garbage
characters. For some reason, every time the strcpy function is called to
copy the string in temp to the array, it fills the 0th element in the strarr
array with garbage characters. Can someone try to compile this...

I'm trying to create a program that gets a string from standard input

Hi experts,
I'm from a Verilog HDL background and trying to learn C. There are a lot of similarities between Verilog and C but the concept of char arrays and strings has me confused. I'd appreciate any help or pointers here.
This is the code, nothing fancy, just basic experiments around char array and string,

#include <string.h>

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:

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,...
