\subsection case-description Description
|
|
|
|
|
|
|
|
|
|
The \c switch statement is used to perform one of several blocks of
|
|
|
|
|
commands depending on whether a specified value equals one of several
|
|
|
|
|
wildcarded values. The \c case statement is used together with the \c
|
|
|
|
|
switch statement in order to determine which block should be
|
|
|
|
|
performed.

|
|
|
|
|
|
|

If the variable \$animal contains the name of an animal, the following
|
|
|
|
|
code would attempt to classify it:
|
|
|
|
|
|
|
|
|
|

|
|
|
