Use the strings.ToTitle function to convert the string into title format, where the first letter of each word is capitalized

The function strings.ToTitle that converts strings into title format is very useful in Go language. It converts the first letter of each word in a string to uppercase letters to achieve a title-style effect.

The following is a sample code using the strings.ToTitle function:

package main

import (
    "fmt"
    "strings"
)

func main() {
    str := "hello, world! welcome to the title format."
    title := strings.ToTitle(str)
    fmt.Println(title)
}

Run the above code, the output result is:

HELLO, WORLD! WELCOME TO THE TITLE FORMAT.

You can see that each character in the original string The first letters of each word are converted to uppercase letters, and the string becomes a title format.

The process of converting strings using the strings.ToTitle function is very simple. You only need to call the function and pass in the string to be converted. The function iterates through each word in the string and converts the first letter of each word to uppercase.

It should be noted that the strings.ToTitle function assumes that the words in the string are separated by spaces by default. If you need to use other delimiters or handle the English abbreviations in the string separately, you can use the strings.Fields function to split the string into slices, then iterate through the slices and apply the strings.ToTitle function to each word.

The following is a sample code that uses the strings.Fields function to split a string:

package main

import (
    "fmt"
    "strings"
)

func main() {
    str := "hello, world! welcome to the title format."
    words := strings.Fields(str)
    for i, word := range words {
        words[i] = strings.ToTitle(word)
    }
    title := strings.Join(words, " ")
    fmt.Println(title)
}

Run the above code, the output result is the same as before:

HELLO, WORLD! WELCOME TO THE TITLE FORMAT.

Use strings.Fields here The function splits the string into slices, then iterates through each word in the slice, applies the strings.ToTitle function to each word, and reassembles the result into a string. The final result is the same as before, with the string transformed into a title format.
