{"@context":"https://schema.org","@type":"FAQPage","mainEntity":[{"@type":"Question","name":"What is a C++ compiler?","acceptedAnswer":{"@type":"Answer","text":"A C++ compiler translates your C++ source code into machine code that can be executed by your computer. PlayCode's online C++ compiler uses Clang/LLVM compiled to WebAssembly, running entirely in your browser. This means instant compilation with no server round-trips, complete privacy, and offline capability."}},{"@type":"Question","name":"Is PlayCode's C++ compiler free?","acceptedAnswer":{"@type":"Answer","text":"Yes, PlayCode's C++ compiler is completely free to use. You can write, compile, and run unlimited C++ code without paying anything. There are no rate limits or compilation quotas. Pro features like AI assistance and private projects are available for subscribers."}},{"@type":"Question","name":"What C++ standard does PlayCode support?","acceptedAnswer":{"@type":"Answer","text":"PlayCode supports modern C++ standards including C++20 via the Clang compiler. You get access to all modern C++ features including auto, lambdas, smart pointers, ranges, concepts, and the complete C++ standard library."}},{"@type":"Question","name":"Can I use the C++ Standard Library?","acceptedAnswer":{"@type":"Answer","text":"Yes! PlayCode includes the full C++ standard library. You can use iostream for input/output, vector and other containers, algorithm for sorting and searching, memory for smart pointers, and all other standard headers."}},{"@type":"Question","name":"Does the C++ compiler work offline?","acceptedAnswer":{"@type":"Answer","text":"Yes, PlayCode works offline after the initial load. The Clang compiler runs entirely in your browser using WebAssembly, so you can keep coding without an internet connection. Your code is saved locally and syncs when you're back online."}},{"@type":"Question","name":"How fast is the online C++ compiler?","acceptedAnswer":{"@type":"Answer","text":"PlayCode's C++ compiler is optimized for speed. After the initial load of the Clang toolchain (about 100MB cached), compilation is near-instant because everything runs locally in your browser. There's no server round-trip, making it faster than traditional online C++ compilers."}},{"@type":"Question","name":"Can I create multi-file C++ projects?","acceptedAnswer":{"@type":"Answer","text":"Yes! PlayCode supports multi-file C++ projects. Create multiple .cpp and .h files using the file tree. Organize your code with header files for declarations and source files for implementations, just like a real C++ project."}},{"@type":"Question","name":"How does browser-based C++ compilation work?","acceptedAnswer":{"@type":"Answer","text":"PlayCode uses browsercc, which compiles Clang/LLVM to WebAssembly. When you click Run, your C++ code is compiled locally in your browser to WebAssembly, then executed using a WASI runtime. This provides native-like performance without any server involvement."}},{"@type":"Question","name":"Is my code private?","acceptedAnswer":{"@type":"Answer","text":"Absolutely. Your code never leaves your browser. Unlike server-based compilers that send your code to remote servers, PlayCode's C++ compiler runs 100% client-side. Your code stays on your device, providing complete privacy and security."}}]}
