Frequently Asked Questions
How do I run Go code online in ZenCompiler?
Simply type or paste your Go code into the editor, provide any optional inputs in the STDIN tab, and click the "Run" button (or press Ctrl/Cmd + Enter). Your code is executed inside a secure cloud Linux container with output streaming directly to the terminal.
Can I use ZenCompiler as an online go compiler for mobile?
Yes! ZenCompiler is fully optimized as a mobile compiler online. You can code, edit, and run Go on any mobile smartphone, iPhone, Android device, or tablet with responsive touch controls, virtual keyboard shortcuts, and full terminal input support without downloading any apps.
Which Go compiler or runtime version is used?
ZenCompiler executes code using Go (1.13), ensuring modern language standards, optimizations, and standard library support.
Can I test concurrency with goroutines and channels online?
Yes. ZenCompiler runs true multithreaded Linux containers where goroutines and channels execute with native concurrency.
How do I take interactive input with fmt.Scanln in Go?
Provide inputs through the STDIN tab or interact directly inside the embedded terminal.
