octave: Notes for the C Programmer
10.2.1 Notes for the C Programmer
---------------------------------
The ‘switch’ statement is also available in the widely used C
programming language. There are, however, some differences between the
statement in Octave and C
• Cases are exclusive, so they don’t ‘fall through’ as do the cases
in the ‘switch’ statement of the C language.
• The COMMAND_LIST elements are not optional. Making the list
optional would have meant requiring a separator between the label
and the command list. Otherwise, things like
switch (foo)
case (1) -2
...
would produce surprising results, as would
switch (foo)
case (1)
case (2)
doit ();
...
particularly for C programmers. If ‘doit()’ should be executed if
FOO is either ‘1’ or ‘2’, the above code should be written with a
cell array like this
switch (foo)
case { 1, 2 }
doit ();
...
