Prototype
Min is an overloaded name; there are actually two min functions.
template <class T> const T& min(const T& a, const T& b);
template <class T, class BinaryPredicate>
const T& min(const T& a, const T& b, BinaryPredicate comp);
Description
Min returns the lesser of its two arguments; it returns the first argument if neither is less than the other.
The two versions of min differ in how they define whether one element is less than another. The first version compares objects using operator<, and the second compares objects using the functors comp.
Definition
Defined in the standard header algorithm, and in the nonstandard backward-compatibility header algo.h.
Requirements on types
For the first version:
For the second version:
-
BinaryPredicate is a model of BinaryPredicate.
-
T is convertible to BinaryPredicate's first argument type and to its second argument type.
Preconditions
Complexity
Example
const int x = min(3, 9);
assert(x == 3);
