std::plus - cppreference.com

template< class T > struct plus;

(until C++14)

template< class T = void > struct plus;

(since C++14)

Function object for performing addition. Effectively calls operator+ on two instances of type T.

[edit] Specializations

The standard library provides a specialization of std::plus when T is not specified, which leaves the parameter types and return type to be deduced.

function object implementing x + y deducing parameter and return types
(class template specialization) [edit] (since C++14) [edit] Member types Type Definition result_type (deprecated in C++17)(removed in C++20) T first_argument_type (deprecated in C++17)(removed in C++20) T second_argument_type (deprecated in C++17)(removed in C++20) T

These member types are obtained via publicly inheriting std::binary_function<T, T, T>.

(until C++11) [edit] Member functions returns the sum of two arguments
(public member function) [edit] std::plus::operator()

T operator()( const T& lhs, const T& rhs ) const;

(constexpr since C++14)

Returns the sum of lhs and rhs.

Parameters Return value

The result of lhs + rhs.

[edit] Exceptions

May throw implementation-defined exceptions.

Possible implementation

constexpr T operator()(const T& lhs, const T& rhs) const 
{
    return lhs + rhs;
}
