Golang : Concatenate (combine) buffer data example



Tags : golang concatenate combine string bytes-buffer

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!
