Clearing the Console in Go on Windows

If you're working with Go on Windows and need to clear the console during the execution of your program, you may have encountered some issues trying various methods.

Failed Approaches

While some solutions suggest using functions like C.system(C.CString("cls")), they may not work consistently across all Windows versions. Additionally, using escape sequences like fmt.Println("\033[2J") may also fail in certain environments.

Effective Solution

The recommended approach to clear the console in Go on Windows is to use the following code:

package main

import (
    "os"
    "os/exec"
)

func main() {
    cmd := exec.Command("cmd", "/c", "cls")
    cmd.Stdout = os.Stdout
    cmd.Run()
}

This approach involves:

1. Creating an exec.Command that runs the Windows command processor (cmd) with the /c flag.
2. Setting the command's standard output to the current process's standard output (os.Stdout).
3. Executing the command to clear the screen.
