How To Program in C++ - Maps and Sets | E13

Learn how to use C++ maps and sets to build faster, cleaner, and more scalable systems. In this video, you’ll master associative containers, including how std::map stores key-value pairs for instant lookups and how std::set guarantees unique, automatically sorted values. Perfect for C++ beginners, game developers, and anyone learning C++ for Unreal Engine and video game development, this lesson focuses on real-world use cases like player scores, IDs, and game systems. This video is part of the Game Creator Accelerator series, helping you build C++ skills with a clear, repeatable path toward a career in video games after office hours. 👉 Learn more about the Game Creator Accelerator Lifetime Mentorship at wulum.com and book a call. --------- 🗣️ BOOK 1:1 Zoom Call: https://calendly.com/tony-566/one-to-one 🎮 FREE Training: https://www.wulum.com/freetraining 🎓 Learn more about my LIFETIME Mentorship: https://www.wulum.com --------- ✔️📱Follow me on X: https://twitter.com/tonymunozdev ✔️📱Say Hi on Instagram: https://www.instagram.com/wulumgames ✔️📱Connect with me on LinkedIn: https://www.linkedin.com/in/tonymunozdev ✔️📱Subscribe to the Channel: https://www.youtube.com/@TonyMunozDev ✔️📱And yes, I also have Facebook: https://www.facebook.com/wulumltd --------- 📺Previous Episode: ✅E01 - Getting Started to C++ Programming https://youtu.be/s1Rejo1q_1k ✅E02 - Variables and Constants in C++ https://youtu.be/yjD-93zCaOA ✅E03 - Operators in C++ https://youtu.be/rOdTMoM7rMc ✅E04 - Conditionals in C++ https://youtu.be/OF3nR1ryTfM ✅E05 - Loops in C++ https://youtu.be/2GUUNiJ5SdU ✅E06 - Functions: https://youtu.be/Ws9_tgD4l8E ✅E07 - Arrays: https://youtu.be/ByqsEejjPsI ✅E08 - Pointers in C++: https://youtu.be/Xf_rtixhiwg ✅E09 - Intro to Object-Oriented-Programming: https://youtu.be/TMn5Kc1pefg ✅E10 - Advanced Object-Oriented Programming: https://youtu.be/pxtj7mwJ7NI ✅E11 - Vectors: https://youtu.be/kzDv78VTh2Y ✅E12 - Lists: https://youtu.be/M-SsWq6CXBw 📺Next Episode: ✅ E14 - Iterators And Algorithms: Uhttps://youtu.be/eBQRFjNw5Oo 📺The Entire Series of C++: ✅ HOW TO PROGRAM in C++ | Beginners FREE Course: https://www.youtube.com/playlist?list=PLjlIN9XAUewgdy9_Qh1dbREj_yk2fd1vG --------- 📺Or Watch Game Dev Career Strategies: 🎮 Quitting My Job To Make Video Games Changed Everything: https://youtu.be/-8bIZ8Wp8Wo 🎮 Game Devs are Not Rational: https://youtu.be/yLwSHSs3mz4 🎮 Stop Hiding Your Work - Get Noticed in the Gaming Industry: https://youtu.be/LLRRze6mVS8 🎮 Why AAA Projects are Failing and How Indies Can Succeed: https://youtu.be/9s7msTOs8kc 🎮 Proof Wins!
