Question

Which among the following is the proper syntax for the template class?

(a) template <typename T1, typename T2>;

(b) Template <typename T1, typename T2>;

(c) template <typename T> T named(T x, T y){  }

(d) Template <typename T1, typename T2> T1 named(T1 x, T2 y){  }

I have been asked this question by my school teacher while I was bunking the class.

This key question is from Template Class topic in chapter Classes of Object Oriented Programming

Answer 1

Correct option is (c) template <typename T> T named(T x, T y){  }

Easiest explanation - The syntax must start with keyword template, case sensitive. Then it should include the typename and a variable to denote it. Then whenever that variable is used, it replaces it with the data type needed.
