    Question 1

    What is the main purpose of function templates in C++?

    • A

      To make functions execute faster

    • B

      To store multiple function definitions in one place

    • C

      To create generic functions that work with multiple data types

    • D

      To restrict a function to only one data type

    Question 2

    Which keyword is used to define a template in C++?

    • A

      template

    • B

      typename only

    • C

      generic

    • D

      template_function

    Question 3

    Consider the following code:

    C++ 
    #include 
using namespace std;

template <typename T>
T add(T a, T b) {
    return a + b;
}

int main() {
    cout << add(5, 10);
}

    What will be the output?

    • A

      Compilation Error

    • B

      5 10

    • C

      15

    • D

      Undefined Behaviour

    Question 4

    Which is the correct syntax for template specialization for int type?

    • A
      C++ 
      template <> int func<int>(int a) { ... }


    • B
      C++ 
      template <> int func<int>(int a) { ... }


    • C
      C++ 
      template <> int func(int a) { ... }


    • D
      C++ 
      specialize template int func(int a) { ... }


    Question 5

    Which of the following is TRUE about variadic function templates?

    • A

      They can accept only integers


    • B

      They are available since C++98

    • C

      They can accept a variable number of template arguments

    • D

      They require all arguments to be the same type

    Question 6

    What is the base case in a variadic function template recursion?

    • A

      When the compiler finds no template arguments left

    • B

      When there are two arguments left

    • C

      When all arguments are of the same type

    • D

       When the last argument is nullptr
