package main

import "fmt"
import "strings"

func main() {
	str1 := "INDIA"
	str2 := "AUSTRALIA"
	str3 := "USA"

	fmt.Println(strings.IndexByte(str1, 'I'))
	fmt.Println(strings.IndexByte(str2, 'T'))
	fmt.Println(strings.IndexByte(str3, 'K'))
}

Output:

0
3
-1

Explanation:

In the above program, we declare the package main. The main package is used to tell the Go language compiler that the package must be compiled and produced the executable file. Here, we imported the fmt package that includes the files of package fmt then we can use a function related to the fmt package.

In the main() function, we created three string variables str1, str2, str3. After that, we used strings.IndexByte() function to get the index of a specified character in the specified string. The strings.IndexByte() function return the integer value. If the specified character is not found in the string then it will return -1.
