lowwer in go

To convert a string to lowercase in the Go programming language, you can use the strings.ToLower() function. Here are the steps to do it:

1. Import the strings package: To use the ToLower() function, you need to import the strings package, which provides string manipulation functions.

import "strings"

1. Declare a variable and assign a string value: Declare a variable and assign the string value that you want to convert to lowercase.

str := "HELLO WORLD"

1. Use the ToLower() function: Call the ToLower() function from the strings package, passing the string variable as the argument. The function returns a new string with all uppercase characters converted to lowercase.

lower := strings.ToLower(str)

After these steps, the lower variable will hold the lowercase version of the original string. You can use the fmt.Println() function to print the lowercase string to the console.

Here is the complete example:

package main

import (
    "fmt"
    "strings"
)

func main() {
    str := "HELLO WORLD"
    lower := strings.ToLower(str)
    fmt.Println(lower)
}

When you run this program, it will output:

hello world

That's how you can convert a string to lowercase in Go using the strings.ToLower() function.
