What version of C does this support?
The playground uses GCC to compile C code, supporting the C99 standard and most commonly used C features.
Interactive C Programming Playground for Developers and Learners
Use this C playground to write, compile, and run C code in real time. Ideal for learning C, testing algorithms, or prototyping low-level logic.
Online C Programming Playground for Developers and Learners
Write, compile, and run C code instantly in your browser with support
for
scanf() and printf(). No installation required
— ideal for learning C, solving algorithm challenges, and experimenting
with systems-level code in real time.
Core Features
- Live C Code Execution: Write, compile, and run C code directly in your browser with real-time results.
- Interactive
scanf()Support: Accept user inputs just like a native terminal program. - Zero Setup: No installation or configuration needed — works instantly in any modern browser.
- Compiler Error Highlighting: Automatically detects and displays syntax and compilation errors for easy debugging.
- Simple UI: Clean, distraction-free environment tailored for learning and low-level experimentation.
- Code Sharing: Share your C code snippets easily with generated links.
Who Is This For?
Playbox C is ideal for:
- Students learning C syntax, data types, and control structures
- Educators teaching core programming concepts like loops, arrays, and pointers
- Systems or embedded developers prototyping low-level logic in C
- Anyone preparing for coding interviews that use C
-
Learners practicing algorithmic challenges with
scanf()input support
Getting Started
- Open the C programming playground in your browser.
-
Write valid C code in the code editor area. You can use standard
functions like
scanf()andprintf()just like in a terminal. -
Enter input values (if your code uses
scanf()) in the input panel — one line per input call. - Click the Run button to compile and execute your code. Output will appear in the output panel.
- Use the Share button to generate a link to your C code snippet.
Tip: If your code has multiple scanf() calls,
enter each input on a new line in the input panel — in the same order.
Frequently Asked Questions
Answers to common questions about the Playbox C Playground and its features.
Can I use scanf() and printf()?
Yes! The playground supports standard C input/output functions. You can simulate terminal input by entering each input on a new line in the input panel.
Do I need to install anything?
Nope! Everything runs directly in your browser. Just open the playground and start writing C code.
Can I save or share my code?
Code sharing is coming soon! We're working on a feature to generate shareable links for your C programs.
Is it free to use?
Yes, the C Playground is completely free and open for anyone to use — no sign-up required.
Does it support external libraries like math.h?
Yes. Standard C libraries such as stdio.h, stdlib.h, and math.h are supported by default.
Can I see output in real time like a terminal?
Yes. The output panel simulates terminal-like behavior, including
real-time handling of printf() and scanf() prompts.
