Hey all, Can someone help me figure out how to pass a dynamic array into a function? Its been giving me some trouble, and my textbook of course doesnt cover the issue. Its probably something simple, but its just not popping into my mind at the moment. My little snippet of code is below. Basically, the studentID array is dynamic so it will fit any length of a Student's Name. What I'm trying to do is place this chunk of code into a...

How is it possible to take the value of a variable (in this case, MODE_CREATE, MODE_UPDATE, etc) and use that as an object property name? In the following example I want 'oIcon' object to have the properties: mode1, mode2, and mode3. This seems simple but I can't quite figure it out... Any ideas anyone?

I am having a little trouble with dynamic memory allocation. I am trying to read a text file and put the contents into a dynamic array. I know I can use vectors to make this easier, but it has to be done using dynamic arrays. I don't know the size of the text file ahead of time, though, so I created a class that includes a method to resize the array. Here is that class: class Data { public: Data(int initialsize);

Hi All, I realize this is not a Palm OS development forum, however, even though my question is about a Palm C program I'm writing, I believe the topics are relevant here. This is because I believe the problem centers around my handling of strings, arrays, pointers and dynamic memory allocation. Here is the problem I'm trying to solve: I want to fill a list box with a list of Project Names from a database (in Palm this is more...

I have a file with a list of times in it in the form hh:mm:ss. The file starts with a single INT like 460. That int is the number of times in the file so I can size my dynamic array correctly. I had to create my array as a type string because of the colons in it. I need to be able to save it in type INT so I can do addition and subtraction on it. I want to be able to add 2 times together or subtract 2 times and get a new time. string...

I need (okay, I want) to make a dynamic array of my class 'Directory', within my class Directory (Can you already smell disaster?) Each Directory can have subdirectories so I thought to put these in an array. The application compiles but aborts without giving me any useful information. What I suspect is happening is infinite recursion. Each Directory object creates an array of Subdirectories each of which has an array of...

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,...

Dear forum friends, With the development of smart home technology, a variety of wireless communication protocols have appeared on the market, such as Zigbee, Z-Wave, Wi-Fi, Bluetooth, etc. Each protocol has its own unique characteristics and advantages, but as a user who is planning to build a smart home system, I am a bit confused by the choice of these technologies.

Let's talk about the concept of autonomous AI software engineers and no-code agents. These AIs are designed to manage the entire lifecycle of a software development project—planning, coding, testing, and deployment—without human intervention. Imagine an AI that can take a project description, break it down, write the code, debug it, and then launch it, all on its own.... Now, this would greatly impact the work of software developers. The idea...

Hello I'm a network technician in training and I need your help. I am currently learning how to create and manage the different types of VPNs and I have a question about LAN-to-LAN VPNs.
