Component type: function

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);

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 function object comp.

Defined in the standard header algorithm, and in the nonstandard backward-compatibility header algo.h.

For the first version:

• T is a model of LessThan Comparable.

For the second version:

• BinaryPredicate is a model of Binary Predicate.

• T is convertible to BinaryPredicate's first argument type and to its second argument type.

const int x = min(3, 9);
assert(x == 3);
