# Scrabble Score
|
|
|
|
Write a program that, given a word, computes the scrabble score for that word.
|
|
|
|
## Letter Values
|
|
|
|
You'll need these:
|
|
|
|
```plain
|
|
Letter Value
|
|
A, E, I, O, U, L, N, R, S, T 1
|
|
D, G 2
|
|
B, C, M, P 3
|
|
F, H, V, W, Y 4
|
|
K 5
|
|
J, X 8
|
|
Q, Z 10
|
|
```
|
|
|
|
## Examples
|
|
"cabbage" should be scored as worth 14 points:
|
|
|
|
- 3 points for C
|
|
- 1 point for A, twice
|
|
- 3 points for B, twice
|
|
- 2 points for G
|
|
- 1 point for E
|
|
|
|
And to total:
|
|
|
|
- `3 + 2*1 + 2*3 + 2 + 1`
|
|
- = `3 + 2 + 6 + 3`
|
|
- = `5 + 9`
|
|
- = 14
|
|
|
|
## Extensions
|
|
- You can play a `:double` or a `:triple` letter.
|
|
- You can play a `:double` or a `:triple` word.
|
|
|
|
## Getting Started
|
|
|
|
Make sure you have read [the C++ page](http://exercism.io/languages/cpp) on
|
|
exercism.io. This covers the basic information on setting up the development
|
|
environment expected by the exercises.
|
|
|
|
## Passing the Tests
|
|
|
|
Get the first test compiling, linking and passing by following the [three
|
|
rules of test-driven development](http://butunclebob.com/ArticleS.UncleBob.TheThreeRulesOfTdd).
|
|
Create just enough structure by declaring namespaces, functions, classes,
|
|
etc., to satisfy any compiler errors and get the test to fail. Then write
|
|
just enough code to get the test to pass. Once you've done that,
|
|
uncomment the next test by moving the following line past the next test.
|
|
|
|
```C++
|
|
#if defined(EXERCISM_RUN_ALL_TESTS)
|
|
```
|
|
|
|
This may result in compile errors as new constructs may be invoked that
|
|
you haven't yet declared or defined. Again, fix the compile errors minimally
|
|
to get a failing test, then change the code minimally to pass the test,
|
|
refactor your implementation for readability and expressiveness and then
|
|
go on to the next test.
|
|
|
|
Try to use standard C++11 facilities in preference to writing your own
|
|
low-level algorithms or facilities by hand. [CppReference](http://en.cppreference.com/)
|
|
is a wiki reference to the C++ language and standard library. If you
|
|
are new to C++, but have programmed in C, beware of
|
|
[C traps and pitfalls](http://www.slideshare.net/LegalizeAdulthood/c-traps-and-pitfalls-for-c-programmers).
