## Primary Purpose
Simple Hello World demonstration program in Go that showcases basic function definition, string formatting, and console output.
## Key Functions
**`greet(name string) string` (L7-9)**
- Pure function that takes a name parameter and returns a formatted greeting string
- Uses `fmt.Sprintf` for string interpolation with "Hello, %s!" template
- No side effects, making it easily testable and reusable
**`main()` (L11-14)**
- Entry point of the Go program
- Calls `greet()` with "World" as argument (L12)
- Prints the resulting message to stdout using `fmt.Println` (L13)
## Dependencies
- `fmt` package (L4) - used for string formatting (`Sprintf`) and console output (`Println`)
## Architecture Notes
- Follows Go's standard main package pattern for executable programs
- Demonstrates separation of concerns: greeting logic isolated in dedicated function
- Clean, minimal structure suitable as template for basic Go programs
- No error handling required as operations are guaranteed to succeed with valid string inputs
