struct minus : public binary_function<T, T, T>;

Description

minus is a binary function object. Its operator() returns the result of x minus y. You can pass a minus

object to any algorithm that requires a binary function. For example, the transform algorithm applies a

binary operation to corresponding values in two collections and stores the result. minus would be used

in that algorithm in the following manner:

vector<int> vec1;

vector<int> vec2;

vector<int> vecResult;
