C++ Templates and Generic Programming

1. What is template specialization?

A way to define a custom implementation for specific template arguments

A method to improve template compilation speed

A requirement for all template definitions

A technique to prevent template instantiation

2. What is the primary purpose of templates in C++?

To create type-safe, reusable code independent of specific data types

To increase program execution speed

To simplify memory management

To replace all function overloading

3. In template metaprogramming, what is SFINAE?

Substitution Failure Is Not An Error—a compiler behavior enabling conditional template compilation

A syntax error that must always be avoided

A directive to force template instantiation

A method to speed up template compilation

4. Which best describes template specialization order?

Full specialization is more specific than partial specialization

Partial specialization is always preferred over full specialization

Specialization order does not affect template selection

Full and partial specializations are equivalent

5. What is the difference between explicit instantiation and implicit instantiation?

Explicit is manual; implicit is automatic when the template is used

Implicit templates are faster than explicit ones

Explicit templates cannot be specialized

There is no practical difference

6. A template member function can be virtual.

True

False

7. Which feature allows a template class to define static data members?

Each instantiation of the template has its own copy of the static member

Static members are shared across all instantiations

Static members cannot be used in templates

Static members must be defined outside the template

8. Template argument deduction allows the compiler to infer template arguments from function arguments.

True

False

9. What is a concept in modern C++ (C++20)?

A named set of constraints on template parameters for clearer semantics

A synonym for template specialization

A compiler directive for optimization

A method to prevent template instantiation

10. Which is true about default template arguments?

They can be specified in function templates and class templates

Function templates cannot have default template arguments

Default arguments must be literals only

They require explicit instantiation

11. What is template recursion used for?

Computing values at compile time through recursive template instantiation

Improving runtime performance of recursive functions

Simplifying template syntax

Avoiding code duplication in regular functions

12. Which keyword declares a function template in C++?

Function

Template

Generic

Typename

13. In a template declaration, both 'typename' and 'class' can be used as keywords. Are they equivalent?

True

False

14. Which statement about function template overloading is correct?

Function templates cannot be overloaded with other function templates

Function templates can coexist with regular function overloads

Overloading requires identical template parameters

Template function names must be unique across all scopes

15. Which of the following is a valid template parameter?

A non-type parameter (e.g., int N)

A type parameter (e.g., typename T)

A template template parameter

All of the above
