|
|
<p>A tuple is a fixed size collection of elements.</p>
|
|
|
|
|
|
|
|
|
|
<p>In the preprocessor library, tuples are represented like macro parameter
|
|
|
|
|
lists. Thus an element of a tuple can be any sequence of tokens that
|
|
|
|
|
constitutes a single macro parameter.</p>
|
|
|
|
|
|
|
|
|
|
<p>Examples of tuples:</p>
|
|
|
|
|
|
|
|
|
|
<pre>
|
|
|
|
|
(const, volatile) // 2-tuple
|
|
|
|
|
(*, /, %) // 3-tuple
|
|
|
|
|
(1, "2", '3', (4,5)) // 4-tuple
|
|
|
|
|
</pre>
|
|
|
|
|
|
|
|
|
|
<p>Tuples can be used for representing structured data.</p>
