Zig

About the Zig Online Compiler

Zig is a modern systems language focused on explicit control, predictable behavior, and straightforward C interoperability. This compiler is useful for testing types, functions, memory handling, and native programs.

Define a public main function and use the standard library for output and core utilities. The compiler can help explore optionals, error unions, comptime behavior, structs, slices, and explicit memory patterns. Keep examples independent of external packages and platform-specific files.

Frequently Asked Questions

What is the Zig Online Compiler?

Zig is a modern systems language focused on explicit control, predictable behavior, and straightforward C interoperability. This compiler is useful for testing types, functions, memory handling, and native programs.

How do I run Zig code?

Enter or edit your program in the Code field, select Run, and read the program result in the Output field.

Which source file does this compiler use?

The submitted code is executed as index.zig, using the file format expected for Zig.

Can this compiler accept interactive program input?

This streamlined compiler contains only Code and Output fields. Programs should include their required test values directly in the source code.

Where are compilation errors displayed?

Syntax errors, compiler messages, runtime errors, and normal program output are displayed together in the read-only Output field.
