minus<T> minus<T> Category: functors Component type: type Description Minus<T> is a function object. Specifically, it is an Adaptable Binary Function. If f is an object of class minus<T> and x and y are objects of class T, then f(x,y) returns x-y. Example Each element in V3 will be the difference of the corresponding elements in V1 and V2 const int N = 1000; vector<double> V1(N); vector<double> V2(N); vector<double> V3(N); iota(V1.begin(), V1.end(), 1); fill(V2.begin(), V2.end(), 75); assert(V2.size() >= V1.size() && V3.size() >= V1.size()); transform(V1.begin(), V1.end(), V2.begin(), V3.begin(), minus<double>()); Definition Defined in the standard header functional, and in the nonstandard backward-compatibility header function.h. Template parameters Parameter Description Default T The function object's argument type and result type.   Model of Adaptable Binary Function, Default Constructible Type requirements T must be a numeric type; if x and y are objects of type T, then x-y must be defined and must have a return type that is convertible to T. T must be Assignable. Public base classes binary_function<T, T, T> Members Member Where defined Description first_argument_type Adaptable Binary Function The type of the first argument: T second_argument_type Adaptable Binary Function The type of the second argument: T result_type Adaptable Binary Function The type of the result: T T operator()(const T& x, const T& y) Adaptable Binary Function Function call operator. The return value is x - y. minus() Default Constructible The default constructor. New members All of minus's members are defined in the Adaptable Binary Function and Default Constructible requirements. Minus does not introduce any new members.
