=={{header|Go}}==

Note that Go doesn't really have a character type. A single quoted character (such as 'd') is by default a ''rune'' (or 32 bit integer) literal representing its Unicode code-point.

<lang go>package main

import "fmt"

type any = interface{}

func showType(a any) {

switch a.(type) {

case rune:

fmt.Printf("The type of '%c' is %T\n", a, a)

default:

fmt.Printf("The type of '%v' is %T\n", a, a)

}

}

func main() {

values := []any{5, 7.5, 2 + 3i, 'd', true, "Rosetta"}

for _, value := range values {

showType(value)

}

}</lang>

{{out}}

<pre>

The type of '5' is int

The type of '7.5' is float64

The type of '(2+3i)' is complex128

The type of 'd' is int32

The type of 'true' is bool

The type of 'Rosetta' is string
