[TynesideLUG] Messing around with bash - fizzbuzz

[Ian Bruntlett]

Hi,

Been messing around with bash... anyone else been dabbling with things?

#!/usr/bin/env bash
# 2021-07-01 fizzbuzz Ian Bruntlett

# fizz_buzz number
# divisible by 3  - return FIZZ
# divisible by 5  - return BUZZ
# divisible by 15 - return FIZZBUZZ
function fizz_buzz()
{
  FIZZ_BUZZ=$1
  declare -i argument=$1
  let "remainder_by_3 = $argument % 3"
  let "remainder_by_5 = $argument % 5"
  let "remainder_by_15 = $argument % 15"

  if [ $remainder_by_15 -eq 0 ]; then
      FIZZ_BUZZ="FIZZ BUZZ"
  elif [ $remainder_by_3 -eq 0 ]; then
      FIZZ_BUZZ="FIZZ"
  elif [ $remainder_by_5 -eq 0 ]; then
      FIZZ_BUZZ="BUZZ"
  fi
}


while [ "$1" != "" ]; do
  fizz_buzz $1
  echo fizz_buzz $1 = $FIZZ_BUZZ
  shift
done
