A helper algorithm for find_if() . Sets result to point to the first element in container c that causes pred to return true , or zero if no such element exists.

Declaration

template< class Container, class Predicate, class T >
void os_find_if( Container& c, Predicate pred, T*& result )

int numbers[ 6 ] = { 2, 4, 8, 15, 32, 64 };
