 Not surprisingly, searching for ``computer'' on \href{https://images.google.com/}{\tt images.google.com} displays rows and rows of these types of machines.

 Many editors will automatically format source code with consistent indenting and line breaks.
 For example, in DrJava (see Appendix~\ref{drjava}) you can indent your code by selecting all text ({\sf Ctrl+A}) and pressing the {\sf Tab} key.

 In this chapter, we'll learn how to store multiple values of the same type using a single variable.
 This language feature will enable you to write programs that manipulate larger amounts of data.

 For example, Exercise~\ref{doubloon} asked you to check whether every letter in a string appears exactly twice.
 One algorithm (which hopefully you already discovered) is to loop through the string 26 times, once for each lowercase letter:
