How to format and print data to a file in Go using fmt.Fprint?

To format and print data to a file in Go using fmt.Fprint, you can follow these steps:

Open the file using the os.Create function or any other file opening function. This will create a file if it doesn't exist, or truncate it if it does.
Create a new File object by passing the file descriptor returned by the file opening function.
Create a Writer object using bufio.NewWriter and pass the file as its parameter. This will provide buffering for performance.
Use fmt.Fprint to format and print the data to the writer object, specifying the data and the writer as parameters.
Use the Flush method of the writer to ensure that all the data is written to the file.
Finally, close the file using the Close method of the file object to free the resources.

Here's an example that demonstrates this process:

package main

import (
    "bufio"
    "fmt"
    "os"
)

func main() {
    // Open the file
    file, err := os.Create("output.txt")
    if err != nil {
        panic(err)
    }
    defer file.Close()

    // Wrap the file with a buffered writer
    writer := bufio.NewWriter(file)

    // Format and print data to the writer
    fmt.Fprint(writer, "Hello, ")
    fmt.Fprint(writer, "World!")

    // Make sure all data is written to the file
    writer.Flush()
}

This example will create a file named "output.txt" in the current directory and write the text "Hello, World!" to it.
