2. State which of the following is True and which is False. If false, explain why. i. The template parameters of a function-template definition are used to specify the types of the arguments to the function, to specify the return type of the function and to declare variables within the function. ii. Keywords typename and class as used with a template type parameter specifically mean "any user-defined class type." iii. The template parameters of a function-template definition are not limited to types introduced by class or typename, but can also include expressions of other types (e.g. built-in int type). iv. Template parameter names among template definitions must be unique. v. Each member-function definition outside a class template must begin with a template header
