From Python to C++ I program in Python and now I am learning C++. What I do with Python is connections to public APIs, API wrappers, data analysis... To learn, besides following tutorials I also like to think about a project (even a small one) and try to develop it because that's how you learn the most. What project ideas can I develop to learn C++? P.S: When I learn more C++ I may also use it to create faster code in Python. https://redd.it/1gltx98 @r_cpp

A 2048 game that I made in C++ I made a 2048 game in c++ for debian. The link to the github repo is https://github.com/hamzacyberpatcher/2048 The build instructions are in the readme file. I just did it as a hobby and it is my first semester in my undergrad degree in c++. I do have prior knowledge in c++ so it helped me a lot. I somehow like c++ more that other languages like python and javascript and like making stuff in it. I hope that you guys will try out the game that I made and give suggestions as well. https://redd.it/1glsu31 @r_cpp

Looking to collaborate I want to collaborate with someone on a project I am working on for inventory management and service request software. I am at the absolutely ground level when it comes to any sort of programming, think C++ is the place to start. Thanks. https://redd.it/1glqc89 @r_cpp

C++ Show and Tell - November 2024 Use this thread to share anything you've written in C++. This includes: * a tool you've written * a game you've been working on * your first non-trivial C++ program The rules of this thread are very straight forward: * The project must involve C++ in some way. * It must be something you (alone or with others) have done. * Please share a link, if applicable. * Please post images, if applicable. If you're working on a C++ library, you can also share new releases or major updates in a dedicated post as before. The line we're drawing is between "written in C++" and "useful for C++ programmers specifically". If you're writing a C++ library or tool for C++ developers, that's something C++ programmers can use and is on-topic for a main submission. It's different if you're just using C++ to implement a generic program that isn't specifically about C++: you're free to share it here, but it wouldn't quite fit as a standalone post.

What’s the difference between int main() and int main(void)? Hi, so we just started learning C++ at uni and we have two different teachers. One of them uses int main() and the other one int main(void). I’m still new to C/C++ and i don’t really understand what’s the difference or which one i should use in what situation. I haven’t really been able to understand it either when i did some research online. Could someone explain it to me like i’m 5 please? https://redd.it/1glbrhm @r_cpp

Is there a Visual Studio blog about C++ features and releases? I used to have the Visual Studio Blog and C++ Team Blog in my RSS feed. In the past year or two, it's been flooded with marketing, Copilot and Unreal stuff, with very few news about C++ features or standard library changes. I swear I used to get articles about new previews, changelogs from the standard library, etc. Is there another blog on the Microsoft website, or is just gone? https://redd.it/1gl36l3 @r_cpp

Self-Taught Hey y’all, I’ve been teaching myself C++ since May & I feel that I’ve hit a wall. I understand the basics(data types, loops, arrays, pointers, stack/heap, etc.) I lack skills in other areas such as polymorphism & memorizing STL. My goal in the end is a video game developer, although for now, im open to other coding jobs to hone my skills. My question is, how should I progress myself to be ready for a job? I don’t have a teacher or a friend that knows coding, just youtube videos and chatgpt. During my time while coding, I’ve done a few projects to build myself a resume, such as a calculator, banking app, number guessing game with some hints, etc. Simple projects. I haven’t gone to college for any tech degree & this is my first language. I don’t really know where/who to ask to give me some advice/insight. Thanks in advance! https://redd.it/1gkodfx @r_cpp

Building a Custom C++ Serializer for Efficient Data Handling I just published a blog post that might interest those of you working with data-heavy applications or game engines. Over the past few months, I’ve been developing a custom C++ serializer tailored for handling complex game components and making the serialization process more efficient and readable. The post dives into: * **Core Design & Structure**: How the serializer is built to handle both basic and custom types. * **Custom Data Types**: Examples of handling types like `Vector2D`, `Vector3D`, and `ModelInfo`. * Add User Data Types: Examples of how to expand the serializer with user defined data types Check it out here: [Building a Custom C++ Serializer for Efficient Data Handling](https://medium.com/@pigeoncodeur/building-a-custom-c-serializer-for-efficient-data-handling-7cec8716de7a) Would love any feedback or thoughts! And if you’re interested in serialization or working on similar projects, let’s connect! https://redd.it/1gkni5c @r_cpp

Got an Offer from ASML Veldhoven as a C++ Developer - Thoughts on the Salary? I recently received an offer from ASML Veldhoven for a C++ developer role. I had cleared all the interview rounds confidently, and I have 3 years of relevant work experience, having worked at one of the biggest engineering companies in Europe in a similar domain. The offer was for 53k euros per year. Honestly, I felt like it wasn’t a fair offer given my experience and background, so I ended up rejecting it. Now I'm curious about the community’s perspective. Was the offer reasonable for someone with my experience, or was I right to feel it fell short? Would love to hear your thoughts and insights on how competitive this offer is in the market. Because honestly I am receiving offers way above this number and was surprised ASML was one of the lowest so far. https://redd.it/1gkcq2v @r_cpp

MSVC C++23 support Any news on MSVC C++23 compiler support? This is the end of 2024 ;)) I know there is something like this https://learn.microsoft.com/en-us/cpp/overview/visual-cpp-language-conformance, and as we can see practically no feature of 23 standart is supported yet, most of STL is implented tho. https://redd.it/1gkdr6e @r_cpp

Should i buy the c++ primer by the Stanley B. Lippman i wan to goo from beginner to the professional level. Should i buy it and i see that the pdf of 5th edition pdf is free to use in the internet so should i but it or see the pdf ????? https://redd.it/1gk4gwm @r_cpp

"No such file or directory" error for header file Hello, I'm following C++ Primer 5th Edition. Reached to point in the fist chapter "Introducing Classes". In this chapter book defines a class named "Sales_item". We are supposed to use the source code files they provide in (http://www.informit.com/title/0321714113) which contains Sales_item.h. Everything went smooth up until now. I downloaded the MS Visual Studio 2012 file and extracted the file contents where my .cpp file is. I get this error message for this following code: #include <iostream> #include "Salesitem.h" int main() { Salesitem item1, item2; std::cin >> item1 >> item2; // first check that item1 and item2 represent the same book if (item1.isbn() == item2.isbn()) { std::cout << item1 + item2 << std::endl; return 0; // indicate success } else { std::cerr << "Data must refer to same ISBN" << std::endl; return -1; // indicate failure } } ERROR message: Sales_item.h: No such file or directory I'm using Visual Studio Code on Linux Mint. p.s: I'm a newbie when it comes to coding so sorry in advance if question isn't well phrased or wasn't asked correctly at all. Thank you for reading. https://redd.it/1gk8saf @r_cpp
