1) Checks if unary predicate p returns Template:cpp for all elements in the range [first, last).
2) Checks if unary predicate p returns Template:cpp for at least one element in the range [first, last).
3) Checks if unary predicate p returns Template:cpp for no elements in the range [first, last).

Parameters
| first, last | - | the range of elements to examine |
| p | - | unary predicate . The expression p(v) must be convertible to bool for every argument |
Return value
1) Template:cpp if unary predicate returns Template:cpp for all elements in the range, Template:cpp otherwise. Returns Template:cpp if the range is empty.
2) Template:cpp if unary predicate returns Template:cpp for at least one element in the range, Template:cpp otherwise. Returns Template:cpp if the range is empty.
3) Template:cpp if unary predicate returns Template:cpp for no elements in the range, Template:cpp otherwise. Returns Template:cpp if the range is empty.
Complexity
At most last - first applications of the predicate
