Every program begins somewhere.

main()

The entry point.

main() represents one of the most fundamental ideas in software — the moment where execution starts, where logic begins to flow, and systems come to life.

Different languages.
Different syntax.
Same concept.

A clear starting point for structure, control, and execution.

Minimal, precise, and instantly recognizable, this design reflects the quiet foundation behind every application, script, or system.

A single call. Everything begins.

Because in code — and often in life — everything starts at main().
