package main import ( "fmt" "os" // "strconv" // "strings" ) func run() error { if len(os.Args) < 4 { return fmt.Errorf("недостаточно аргументов") } gridSize := os.Args[1] + "x" + os.Args[2] fillPercentage := os.Args[3] + "%" config := gridSize + " " + fillPercentage file, err := os.Create("config.txt") if err != nil { return err } defer file.Close() _, err = file.WriteString(config) if err != nil { return err } return nil } func main() { err := run() if err != nil { fmt.Println(err) } }

In this code, the run function takes command line arguments for grid size and fill percentage, combines them into a configuration string, and writes this configuration to a file named config.txt.

The main function calls the run function and prints any errors that occur during the execution.

To run this code, you need to provide three command line arguments: grid size (e.g. 10 10), fill percentage (e.g. 50%), and the file name where the configuration will be saved (config.txt in this case).

You can run this code by compiling it and then running the compiled executable with the required command line arguments. For example:

go build main.go
./main 10 10 50

This will create a file named config.txt with the configuration "10x10 50%".
