Description

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

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

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

in that algorithm in the following manner:

vector<int> vec1;
