# Grains

Calculate the number of grains of wheat on a chessboard given that the number
on each square doubles.

There once was a wise servant who saved the life of a prince. The king
promised to pay whatever the servant could dream up. Knowing that the
king loved chess, the servant told the king he would like to have grains
of wheat. One grain on the first square of a chess board. Two grains on
the next. Four on the third, and so on.

There are 64 squares on a chessboard.

Write code that shows:
- how many grains were on each square, and
- the total number of grains

## For bonus points

Did you get the tests passing and the code clean? If you want to, these
are some additional things you could try:

- Optimize for speed.
- Optimize for readability.

Then please share your thoughts in a comment on the submission. Did this
experiment make the code better? Worse? Did you learn anything from it?

## Testing

In order to run the tests for this track, you will need to install
DUnitX. Please see the [installation](http://www.exercism.io/languages/delphi/installation) instructions for more information.

### Loading Exercises into Delphi

If Delphi is properly installed, and `*.dpr` file types have been associated with Delphi, then double clicking the supplied `*.dpr` file will start Delphi and load the exercise/project.  `control + F9` is the keyboard shortcut to compile the project or pressing `F9` will compile and run the project.

Alternatively you may opt to start Delphi and load your project via. the `File` drop down menu.

### When Questions Come Up
We monitor the [Pascal-Delphi](https://gitter.im/exercism/Pascal-Delphi) support room on [gitter.im](https://gitter.im) to help you with any questions that might arise.

### Submitting Exercises

Note that, when trying to submit an exercise, make sure the exercise file you're submitting is in the `exercism/delphi/<exerciseName>` directory.

For example, if you're submitting `ubob.pas` for the Bob exercise, the submit command would be something like `exercism submit <path_to_exercism_dir>/delphi/bob/ubob.pas`.
