Multiplying Integers
Interpreters, Iteration 6
User Story
Your client interrupts you with this story. You figure it should be easy enough to add now (before you deal with adding strings).
User Story #6: Interpreter evaluates a two-value product.
A Hobbes program can be the multiplication of two integers.
Example: 2 * 3 evaluates to 6.
Some languages allow "a" * 4 which results in
"aaaa". I'm sure if your client wants this, you'll be
told.
On Your Own
This is an iteration you'll do on your own. Here are some things to consider:
- There is an
OperatorETIR.Operator.MULTIPLY. - Write some great tests.
- Don't be afraid to duplicate some code. Don't duplicate too much code
- Try to remove smells
- Are your variable and method names honest and accurate? If not, try a rename refactoring.
- Is a method getting too long (i.e., more than five lines of code)? Try an extract-method refactoring.
- Try multiple solutions.
