Implement a templated C++ class Vector that manipulates a numeric vector. Your class should be templated with any numerical scalar type T, which supports the operations + (addition), − (subtraction), and * (multiplication). In addition, type T should have constructors T(0), which produces the additive identity element (typically 0) and T(1), which produces the multiplicative identity (typically 1). Your class should provide a constructor, which is given the size of the vector as an argument. It should provide member functions (or operators) for vector addition, vector subtraction, multiplication of a scalar and a vector, and vector dot product. Write a class Complex that implements a complex number by overloading the operators for addition, subtraction, and multiplication. Implement three concrete instances of your class Vector with the scalar types int, double, and Complex, respectively.
