Definido en la cabecera <algorithm>
template< class RandomIt >
void sort_heap( RandomIt first, RandomIt last );
(1)
template< class RandomIt, class Compare >
void sort_heap( RandomIt first, RandomIt last, Compare comp );
(2)

comp - comparison function which returns ​true if the first argument is less than the second.

The signature of the comparison function should be equivalent to the following:

 bool cmp(const Type1 &a, const Type2 &b);

The signature does not need to have const &, but the function must not modify the objects passed to it.
The types Type1 and Type2 must be such that an object of type RandomIt can be dereferenced and then implicitly converted to both of them. ​

Requerimientos de tipo
-
RandomIt debe reunir los requerimientos de ValueSwappable y RandomAccessIterator.
-
The type of dereferenced RandomIt must meet the requirements of MoveAssignable and MoveConstructible.
