How to join two files in Golang 1.20
0In this video we are going to generate source code for the GoLang Program, How to join two files using chatGPT.
After generating we will verify and run the generated code.
IMPORTANT NOTE on SOURCE CODE: only source code that are acceptable by the youtube description box will be displayed.
##############SOURCE CODE#########################
package main
import (
"fmt"
"io/ioutil"
"os"
)
func main() {
// open first file
file1, err := os.Open("file1.txt")
if err != nil {
panic(err)
}
defer file1.Close()
// open second file
file2, err := os.Open("file2.txt")
if err != nil {
panic(err)
}
defer file2.Close()
// read contents of first file
content1, err := ioutil.ReadAll(file1)
if err != nil {
panic(err)
}
// read contents of second file
content2, err := ioutil.ReadAll(file2)
if err != nil {
panic(err)
}
// create new file to store combined content
newFile, err := os.Create("newFile.txt")
if err != nil {
panic(err)
}
defer newFile.Close()
// write contents of both files to new file
_, err = newFile.Write(content1)
if err != nil {
panic(err)
}
_, err = newFile.Write(content2)
if err != nil {
panic(err)
}
fmt.Println("Files have been joined successfully.")
}
##############END OF SOURCE CODE#########################
Below is the explanation for the program:
This program uses the os and io/ioutil packages to open, read, and write files.
The os.Open function is used to open the two input files, and ioutil.ReadAll is used to read the contents of each file into memory.
Then, the program creates a new file using os.Create, and writes the contents of both input files to the new file using the Write method.
Finally, the program prints a message to indicate that the files have been joined successfully.
