如何找到 Go 字串中某個字元的索引？

在Go with Strings 套件中尋找字元索引

您可以使用Index 函數從字串中擷取字串中字元的索引

用法範例：

package main

import (
    "fmt"
    "strings"
)

func main() {
    str := "chars@arefun"
    char := "@"

    // Find the index of the character using strings.Index
    index := strings.Index(str, char)

    if index != -1 {
        // If the character was found, split the string based on the index
        chars := str[:index]
        arefun := str[index+1:]

        fmt.Println("Index:", index)
        fmt.Println("chars:", chars)
        fmt.Println("arefun:", arefun)
    } else {
        fmt.Println("Character not found")
    }
}

輸出：

Index: 5
chars: chars
arefun: arefun
