Introduction

I created it as a small story of Bash programming. I am writing an article at a rapid pace for some reason. By the way, this is the third installment.

What is FizzBuzz?

For FizzBuzz, please check here. Count up from 1

--Display "Fizz" when divisible by 3 --Display "Buzz" when divisible by 5 --Display "FizzBuzz" when it is divisible by both

And so on.

Source

#!/bin/bash

echo -n "Please input number => "
read num

for i in $(seq 1 ${num})
do
  if (( $i % 3 == 0 && $i % 5 == 0 ))
  then
    echo "FizzBuzz"
  else if (( $i % 3 == 0))
    then
      echo "Fizz"
    else if (( $i % 5 == 0 ))
      then
        echo "Buzz"
      else
      echo $i
      fi
    fi
  fi
  sleep 1
done

Execution result

$ ./fizzbuzz.sh
Please input number => 15
1
2
Fizz
4
Buzz
Fizz
7
8
Fizz
Buzz
11
Fizz
13
14
FizzBuzz

At the end

You can make it by applying a program that becomes aho when there are multiples of 3 and a character string of 3.

By creating this program

--Algorithm --Conditional expression --Conditional operator --read command

I understand.
