Animal.txt
January 12, 2021
Today’s task is from a beginning programmer, who starts with an input file called animal.txt:
There once was a Dog
Wednesday he ate Apples
Thursday he ate Apples
Friday he ate Apples
Saturday he ate carrots
There once was a Bear
Tuesday he ate carrots
Wednesday he ate carrots
Thursday he ate chicken
He wants to create this output:
Food: Apples Animals who ate it: 1
=======
Dog
Food: Carrots Animals who ate it: 2
========
Bear
Dog
Food: Chicken Animals who ate it: 1
========
Bear
He gave a complicated awk solution that didn’t work; it produced duplicate lines of output in those cases
where the same animal ate the same food on multiple days.
Your task is to write a program to produces the desired transformation form input to output. When
you are finished, you are welcome to read or run a suggested solution, or to post your own solution or
discuss the exercise in the comments below.
