C/C++ Programming Compiler vs Infinite Digits

Write C/C++ code directly on your iPhone, iPad and iPod Touch! This app supports the latest C/C++ compilers and is ideal for learning and testing code snippets! C++ is a general-purpose programming language created by Bjarne Stroustrup as an extension of the C programming language, or "C with Classes". The language has expanded significantly over time, and modern C++ has object-oriented, generic, and functional features in addition to facilities for low-level memory manipulation. Features: - Compile and run your program - View program output or detailed error - Choose between C++ compiler standards (ISO/IEC 14882) namely: C++98, C++03, C++11, C++14, C++17, C++20, C++23 - Multithreading support - Custom keyboard for easy input of frequently used characters - Optimized for connecting with external physical/bluetooth keyboard - Advanced source code editor with syntax highlighting, bracket completion and line numbers - Open, save, import and share C/C++ files. Supports File Sharing with iTunes Connect, AirDrop and iCloud. - Language reference Limitations: - Internet connection is required for compilation - Maximum program running time is 20s - One file can be run at a time - Some file system, network and graphics functions may be limited - This is a batch compiler; interactive programs are not supported. For example, if your program provides an input prompt, enter the input in the Input tab prior to compilation.

How many digits of pi can you remember—and how much do you really know about the numbers behind them? Infinite Digits turns mathematical constants into a focused, rewarding learning experience. Memorize digits at your own pace, test your recall under pressure, explore the formulas that make each constant meaningful, and watch your skills grow over time. Go beyond π Study eight essential mathematical constants: • Pi (π) • Euler’s Number (e) • The Golden Ratio (φ) • The Euler–Mascheroni Constant (γ) • Square Root of 2 (√2) • Square Root of 3 (√3) • Natural Logarithm of 2, ln(2) • Apéry’s Constant, ζ(3) BUILD A MEMORY THAT LASTS Training Mode gives you a calm, flexible place to practice. Choose a constant, set the number of digits, enter the sequence from memory, and get clear feedback on your result. Start with a short run or work toward hundreds and thousands of digits—the pace is yours. TAKE ON THE CHALLENGE Ready to find your limit? Challenge Mode offers seven levels, from a quick 9-digit warm-up to a legendary 9,999-digit test. New levels unlock as your continuous correct prefix improves, giving every session a clear goal and every personal best a reason to keep going. SEE MORE THAN A SCORE A single percentage never tells the whole story. Infinite Digits tracks both your longest correct prefix and your position-by-position accuracy, so you can see where your recall is strong and where it breaks down. Review recent sessions, compare constants, follow progress charts, and turn small improvements into lasting momentum. UNDERSTAND BEFORE YOU MEMORIZE The Formula Explorer connects digits to ideas. Interactive visuals, sliders, core formulas, and guided steps help you see how each constant appears in geometry, calculus, logarithms, sequences, and number theory. EXPLORE THE STORIES BEHIND THE SYMBOLS Open the built-in mathematical encyclopedia to discover each constant’s historical timeline, real-world and scientific applications, and surprising facts. Learn how π evolved from ancient approximations, why e appears in growth and decay, how φ connects to geometry, and why ζ(3) still fascinates mathematicians. CALCULATE WITH PRECISION Need more digits for study, reference, or curiosity? Use the Constants Calculator to generate high-precision values, adjust the number of decimal places, preview the result, and copy the full value when you need it. DESIGNED FOR FOCUSED PRACTICE • Eight constants in one beautifully organized app • Adjustable training length • Seven progressively challenging recall levels • Detailed session history and performance statistics • Longest-prefix and positional-accuracy tracking • Interactive formula visualizations • Historical timelines, applications, and facts • High-precision constants calculator • Ten distinctive light and dark color themes • Optional sound effects and haptic feedback • Practice progress saved locally on your device • Interface support for English, German, French, Spanish, Japanese, Korean, Simplified Chinese, and Traditional Chinese FOR CURIOUS MINDS AT EVERY LEVEL Infinite Digits is made for students, teachers, math enthusiasts, trivia lovers, competitive memorizers, and anyone who enjoys turning a difficult goal into a daily habit. You do not need to be a mathematician. Start with a few digits, learn the pattern, and build from there. Your next personal best begins with one more digit. Download Infinite Digits and discover how far your memory—and your curiosity—can go.
