Golang : Concatenate (combine) buffer data example
At previous tutorial on how to concatenate ( combine ) strings data, a reader asked how to concatenate data inside a buffer.
In Golang, the +=
symbol equals to x = x + somethingnew
and we will use the +=
to combine the buffer data(which is converted to string type with the built in String()
and strconv.Itoa()
functions.
Here you go :
package main
import (
"bytes"
"fmt"
"strconv"
)
func main() {
var buffer bytes.Buffer
for i := 0; i < 2; i++ {
buffer.WriteString("a")
}
s := buffer.String()
// s is now aa
for i := 0; i < 8; i++ {
s += strconv.Itoa(i)
}
// s is now aa01234567
s += buffer.String()
// s is now aa01234567aa
fmt.Println(s)
}
Output :
aa01234567aa
Happy Coding!
