The any_of() function in C++ boost library is found under the header ‘boost/algorithm/cxx11/any_of.hpp’ which tests the elements of a sequence and returns true if they any of the elements share the property given. It takes a sequence and a predicate, and returns true if the predicate returns true for any given element in the sequence.
bool any_of ( InputIterator first, InputIterator last, Predicate p )
bool any_of ( const Range &R, Predicate p)
Parameters: The function accepts parameters as described below:
- first: It specifies the input iterators to the initial positions in a sequence.
- second: It specifies the input iterators to the final positions in a sequence.
- p: It specifies a unary predicate function that accepts an element and returns a bool.
- R: It is the complete sequence.
Return Value: The function returns true if the given predicate is true on any of the element of the sequence, else it returns false.
Below is the implementation of the above approach:
at least one element is odd
at least one element is less than 7
