Associative Array Exercise
- Two more common applications for associative arrays are
- Finding a subset of unique items in a list
- Counting the number of instances of items in a list
- Your task is to start with the "unique" example script as a template to
create a script called "count" as described above
Exercise |
- Run the "unique" example like this:
unique < unique.dat
(or you can type one word per line as input on your keyboard)
- Copy the "unique" example into a new script file called "count".
- Modify it to count the number of instances of items in a list
- HINT1: You can use the += operator to add to a value.
- HINT2: Print both the KEY and the VALUE for each key.
