Golang : How to convert character to ASCII and back
Problem:
ASCII or American Standard Code for Information Interchange is used to represent characters and device control in computers. How to convert a character to ASCII and back to a character?
Solution:
To get the ASCII value of a character, simply type cast the character with int()
function and make sure the character is a rune
instead of type string
. To revert it back or to convert integer ASCII value to a character, type cast the integer with string()
function.
Here you go!
package main
import (
"fmt"
)
func main() {
// character to ASCII
char := 'a' // rune, not string
ascii := int(char)
fmt.Println(string(char), " : ", ascii)
// ASCII to character
asciiNum := 65 // Uppercase A
character := string(asciiNum)
fmt.Println(asciiNum, " : ", character)
}
Output:
a : 97
65 : A
