Find last element in vector c++
Web21 hours ago · Usually what we want for the initial element is some identity element for the value type of the range with respect to the given binary operator. Given any object x of type T and operation f, the identity element id is one for which f(id,x) == x. For example, the identity element for the pair int, operator+ is 0. For int, operator* it’s 1.
