CS++ Java IDE vs C++ Starter

CS++ Java IDE is a focused, offline Java environment for students learning to code — and a complete AP Computer Science A practice platform. Write code in a real Java IDE designed for touch. Run programs instantly with the bundled Java runtime — no internet, no compiler setup, no accounts. Tap Run and your code executes on your device. WHAT'S INCLUDED • Multi-file Java editor with syntax highlighting, line numbers, auto-indent, and a templates menu • Bundled Java runtime — runs your code locally, even in airplane mode • A debugger: tap a line number to set a breakpoint, then step through your program and watch its variables • Unit 1 free: 13 starter problems covering primitive types, output, and your first algorithm • Full AP CSA course (one-time $9.99 unlock): 11 units, 50+ inline coding challenges, persistent progress REAL JAVA, WELL PAST THE AP SUBSET Everything AP CSA uses, and much more of the language: the java.util collections (ArrayList, LinkedList, HashMap, TreeMap, HashSet, TreeSet, ArrayDeque, Stack, PriorityQueue), your own generic classes, inner and anonymous classes, interfaces with default methods, lambdas, method references, streams, Optional, and exceptions, including your own. It is tested against the real JDK, so your programs print what Java prints, and compile errors read like javac's. DESIGNED FOR LEARNING • Each challenge tests your output against expected results • Inline error messages with the exact line and what went wrong • "Format" button cleans up indentation in one tap • Templates menu loads 14 starter projects: Scanner input, reading a text file, ArrayList, 2D arrays, inheritance, and the four AP FRQ types • Progress saved on-device — pick up where you left off UNIVERSAL Built for iPhone and iPad. The editor and console scale from 4-inch phones to 13-inch iPads, with a full-bleed editor on phones to maximize coding space. OFFLINE-FIRST No account creation. No login. No data sent off your device. Lessons, code, and progress all live in the app's local storage. Use it on a flight, in a classroom with no Wi-Fi, or anywhere. THE FULL AP CSA COURSE Unit 1 is free. Unlock all 11 units for $9.99 (one-time, no subscription): 1. Primitive Types & Output 2. Using Objects 3. Boolean Expressions & if 4. Iteration 5. Writing Classes 6. Array 7. ArrayList 8. 2D Array 9. Inheritance 10. Recursion 11. Sorting & Searching Built by Yellow Dart Publishing for csplusplus.com — the College Board–aligned CS curriculum used by teachers across the U.S.

C++ Starter is a programming and learning environment for beginners. Learn by writing and running real C++ code, progressing from basic syntax to algorithms, games, graphical interfaces, and network projects. Write, compile, and run C++17 programs directly on iPhone, iPad, and Mac. Provide input and inspect output without setting up a compiler toolchain yourself. Learn by writing code Start with 20 free C++ lessons covering variables, input and output, conditions, loops, functions, strings, containers, structs, and classes. Continue with seven advanced courses through Learning Pro: - C++ Data Processing and the Standard Library - Algorithms and Problem Solving - C++ Object-Oriented Programming and Project Organization - Console Tool Projects - Introduction to Game Programming - Introduction to GUI Programming - Introduction to HTTP Programming Courses are available in English, Simplified Chinese, and Japanese, with explanations, examples, exercises, and reference implementations. Console exercises are checked locally using test inputs and outputs. Game and GUI exercises include interactive checklists. Explore beyond the code Discover the history and applications of C++, learn coding conventions, explore popular libraries, and find recommended books to guide your next steps. App news and contextual tips introduce new features and offer practical guidance for programming and learning. From console programs to interactive projects - Build data-processing tools and algorithms with the standard library - Learn game and graphics programming with raylib - Explore widgets, layouts, and events with TGUI - Learn HTTP requests and server endpoints with CPR and Crow - Edit and run client and server code within the same project A workspace for every screen - C++17 and multiple source files - On-device compilation and execution - Preset input and interactive input - Program output and compiler diagnostics - Automatic code saving - Tab navigation on iPhone, with a landscape layout that leaves more room for your work - Project-focused sidebars on iPad and Mac, with quick access to courses and Explore - Light and Dark Mode support - Multiple projects and advanced library, display, and server settings with IDE Pro Local programming, networking when needed No account registration is required. Project code stays on the current device, and compilation and execution take place locally without uploading your source code to the developer’s servers. Network programs can access external services; data included in requests is sent to the servers specified by your code. Free features and optional purchases The complete C++ Basics course and one editable local workspace for standard C++ are free. IDE Pro is an optional one-time purchase that unlocks multiple projects and advanced project settings. Learning Pro provides access to paid courses for 1, 3, or 12 months, with no automatic renewal. During the access period, you can study all paid courses available in your region. The editing and execution features needed for course exercises are included; no separate IDE Pro purchase is required. From your first program to games, interface tools, and HTTP endpoints, start building with C++ Starter.
