      Thank you so much for your support and enthusiasm for my course, it means a lot! For this course we won't cover C++ builder because it is paid software and i wanted to use only the free tools so that it is accessible for everyone and that's why we will use Visual Studio. I promise the skills you'll learn will be useful in different programming languages and environments.

    how can i do that?

    I kind of miss programming in C++. I'm a full time developer and we don't use C++ at my company. I have my own home projects in C++ that need working on, I just never feel like it after spending the day working on other people's code, so I go months at a time without working on the projects I'd like to finish. BTW, how's the kitten doing?

    • @CodeBeauty
      @CodeBeauty  Před rokem

      I completely understand how you feel! When I used to work as a programmer for other companies, I often found myself too exhausted to work on my personal projects outside of work hours. It can be tough to stay motivated when you've spent all day working on code, but i would strongly encourage you not to give up on your passion for C++. Try dedicating some time, an hour per day or whatever you find comfortable to spare it for something that's making you happy because, in the long run, it's more important than any material gain.

    It’s just printing out whatever’s in the uninitialised memory, I was surprised it ran the first time, I thought it would throw out a null reference exception, but it probably worked because of the default constructor

      You need copy ctors only if your class has pointers. Otherwise, it can be copied even without a copy constructor 😊

    Using uninitialized variables causes UB (Undefined Behavior). This becomes dangerous when it comes to uninitialized pointers because it could cause segmentation fault (don't forget nullptr :))

    Impressive and certainly very useful but to pass a strict Turing test (it seems) more advancement is required.

    • @CodeBeauty
      @CodeBeauty  Před rokem +2

      In order to create a machine that will pass the Turing test, you first need to have a good understanding of basic programming concepts, and be able to grasp them in depth through practice. Afterwards, it is essential to upgrade your knowledge with an understanding of artificial intelligence, machine learning algorithms, natural language processing techniques, and other related concepts. You have made a good decision by choosing C++ for this endeavor, as it is a high-performance programming language that is utilized in many complex systems, including artificial intelligence. ❤
