General FizzBuzz: Difference between revisions

Line 47:

This is a two-step solution:

* First, we get the parameters, and

** generate a file with the list of numbers (writing ~~direcly~~ to that file)

** generate a file with the list of numbers (writing directly to that file)

** generate a custom awk-program for that special case (redirecting standard-output)

* the custom program is run, and does the actual work to output the desired result

awk -f fizzbuzzGenerate.awk > fizzbuzzCustom.awk

awk -f fizzbuzzCustom.awk numbers.txt

</~~lang~~>

<lang bash>awk -f fizzbuzzGenerate.awk input.txt > fizzbuzzCustom.awk

awk -f fizzbuzzCustom.awk numbers.txt</lang>

;Input:

3 Fizz

5 Buzz

7 Baxx
