std::minus

性病：减

Defined in header ​​
template< class T > struct minus;​(until C++14)
template< class T = void > struct minus;​(since C++14)

函数对象，用于执行减法。有效呼叫operator-关于类型的两个实例T...

专门性

The standard library provides a specialization of std::minus when T is not specified, which leaves the parameter types and return type to be deduced. minus function object implementing x - y deducing argument and return types (class template specialization)minusfunction object implementing x - y deducing argument and return types (class template specialization)(since C++14)
minus<void>function object implementing x - y deducing argument and return types (class template specialization)

成员类型

TypeDefinition
result_type(deprecated in C++17)T
first_argument_type(deprecated in C++17)T
second_argument_type(deprecated in C++17)T

成员函数

operator()returns the difference between two arguments (public member function)

STD：：减：：操作员%28%29

T operator()( const T& lhs, const T& rhs ) const;​(until C++14)
constexpr T operator()( const T& lhs, const T& rhs ) const;​(since C++14)

返回lhs和rhs...

参数

lhs, rhs-values to subtract from one another

返回值

结果lhs - rhs...

例外

%280%29

可能的实施

ConstT算子%28%29%28 const T&lhs，const T&rhs%29 const{返回lhs-rhs；}
