Problem 1
State which of the following statements are true and which are false. If a statement is \(f a / s e,\) explain why. a. 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. b. Keywords typename and class as used with a template type parameter specifically mean "any user-defined class type." c. A function template can be overloaded by another function template with the same function name. d. Template parameter names among template definitions must be unique. e. Each member-function definition outside a class template must begin with a template header. f. A friend function of a class template must be a function-template specialization. g. If several class-template specializations are generated from a single class template with a single static data member, each of the classtemplate specializations shares a single copy of the class template's static data member.
Problem 5
Overload function template printarray of Fig. 14.1 with a nontemplate version that specifically prints an array of character strings in neat, tabular, column format.
Problem 6
Write a simple function template for predicate function isEqualto that compares its two arguments of the same type with the equality operator \((==)\) and returns true if they are equal and false if they are not equal. Use this function template in a program that calls isEqualto only with a variety of built-in types. Now write a separate version of the program that calls isEqualTo with a user-defined class type, but does not overload the equality operator. What happens when you attempt to run this program? Now overload the equality operator (with the operator function) operator==. Now what happens when you attempt to run this program?
Problem 8
Write a program with class template array. The template can instantiate an Array of any element type. Override the template with a specific definition for an Array of float elements (class Array< float >). The driver should demonstrate the instantiation of an Array of int thRough the template and should show that an attempt to instantiate an Array of float uses the definition provided in class Array< float \(>\)
Problem 11
What is the relationship between function templates and overloading?
Problem 12
Why might you choose to use a function template instead of a macro?
Problem 13
What performance problem can result from using function templates and class templates?
Problem 14
The compiler performs a matching process to determine which functiontemplate specialization to call when a function is invoked. Under what circumstances does an attempt to make a match result in a compile error?
Problem 15
Why is it appropriate to refer to a class template as a parameterized type?
Problem 19
Why might you use a nontype parameter with a class template for a container such as an array or stack?
