How to Determine the Character Index in Golang

In Golang, finding the index of a specific character may differ from the indexing of character fragments. To locate the index of a given character, such as "@" in a string, utilize the Index function from the strings package.

To illustrate:

import "fmt"
import "strings"

func main() {
    // Define the input string
    input := "chars@arefun"

    // Determine the character index
    index := strings.Index(input, "@")

    fmt.Printf("Index of '@': %d\n", index)

    // If the character is found (i.e., index is not -1)
    if index != -1 {
        // Extract the characters before the delimiter
        charsBefore := input[:index]
        // Extract the characters after the delimiter
        charsAfter := input[index+1:]

        fmt.Printf("Characters before '@': %s\n", charsBefore)
        fmt.Printf("Characters after '@': %s\n", charsAfter)
    } else {
        fmt.Println("Character '@' not found")
    }
}

In this example:

• The Index function is used to find the index of the "@" character in the input string.
• If the character is found, the characters before and after the "@" character are extracted and printed.
• If the character is not found, an appropriate message is displayed.
