package main

import "fmt"

func main() { 
  str := "hello"
  for i := 0; i < len(str); i++ {
    fmt.Printf("%b %s\n", str[i], string(str[i]))
  }
}

package main

import ( 
  "bytes"
  "fmt"
)

func main() { 
  str := "something"
  buf := bytes.NewBufferString(str)
  for i := 0; i < 1000; i++ {
    buf.Write([]byte(randomString()))
  }
  fmt.Println(buf.String())
}

func randomString() string { 
  ret := "pretend-this-is-random"
  return ret
}

package main

import "fmt"

func main() { 
  str := "XBodyContentX"

  fmt.Println(content)
}
