Why is it returning a letter?

Question

go

There is a code

package main

import "fmt"

func main() {
  i := 65
  fmt.Println(string(i))
}

why does the code return A?

Answer 1

Because 65 is the code for the English letter "A".
If you want to display 65, you need to use either the strconv or fmt module.

package main

import "fmt"
import "strconv"

func main() {
  var i int64 = 65
  fmt.Println(strconv.FormatInt(i, 10))
  // или так
  fmt.Printf("%d\n", i)
}
