For a better understanding of this example, we always recommend you to learn the basic topics of Golang programming listed below:
To convert a sting to a byte array we need to translate the sequence of chjaracters into a equence of bytes. For this translation we use an instance of charset. This specifies a mapping between a sequence of characters and a sequence of bytes. A charset or character set refers to the composite number of different characters that are being used and supportedby the computer hardware and software.
Here we are showing how to convert the string to byte array in the Go language. Here variable str is holding the string to be converted. And variable byteStr for holding the result. Finally, the string is converted using []byte(str) and print the result. Given below are the steps which are used in the Go program.
STEP 1: Import the package fmt
STEP 2: Start function main()
STEP 3: Declare the string variable str
STEP 4: Consider variable byteStr for holding the result
STEP 5: The string is converted using []byte(str)
STEP 6: Finally print the variable byteStr using fmt.Println()
package main
import (
"fmt"
)
func main() {
var str string
str = "Hello World"
byteStr:= []byte(str)
fmt.Println(byteStr)
}
