A number from 1 to 100 is output to the terminal, and when it is a multiple of 3, it is output as Fizz as a character string instead of a number, when it is a multiple of 5, it is output as Buzz, and when it is a multiple of both, it is output as FizzBuzz. I will write a commentary on the problem of making a program.
def fizz_buzz num = 1 while (num <= 100) do if (num % 3 == 0) && (num % 5 == 0) puts "FizzBuzz" elsif (num % 3) == 0 puts "Fizz" elsif (num % 5) == 0 puts "Buzz" else puts num end num = num + 1 end end fizz_buzz
Assign 1 to the variable num, and output FizzBuzz when num is 100 or less in the while method, and when it is a multiple of 3 and a multiple of 5. Output as Fizz when it is a multiple of 3. Buzz and output when it is a multiple of 5. Otherwise, it outputs num and adds 1 to num at the end.
