What's Next ?
Homework (all)• 3 new Functions from clojure.core• 4 new functions (exercises) with Unit Testing
• (car-tax [c1 c2 c3 c4])• (bank-deposit ac1 10)• (bank-withdraw ac1 5)• (bank-assessment ac1)
What's Next ?car-tax [vector-of-cars]
Car must be a struct with owner-name, car-type, cur-speed and license-plate. Cars that current speed is grater than 100 pay 10 plus 20 each 1 beyond 100. This func must add the property tax with proper value to the car.
What's Next ?
bank-* [account]
Bank account is a struct with name and value. All changes must be persistent(ref) and you must pass the account in all operations. You must use STM for this functions as well.
