1. The definition of an array of pointers to functions of size (ol that take two integers as input parameters, and of return type of bool. a. bool (*pte[n])int a, int b) b. bool *ptr(int a, int b) c. 2. 3. d. T (*ptr)(T&) e. Te function(T&) T* ptr ToObject : a. names a pointer that holds the address of a region of type T b. names a pointer that holds the address of a region of type T () (T6) C. names a function that receives a reference to an object of type Te and returns the address of a region that holds an object of type T d. All of the above e. None of the above T("ptr ToFunction)(T&): a. names a pointer that holds the address of a region of type T b. names a pointer that holds the address of a region of type T (*) (76) C names a function that receives a reference to an object of type TG and returns the address of a region that holds an object of type T d. All of the above e. None of the above T* function(T&): a. names a pointer that holds the address of a region of type T b. names a pointer that holds the address of a region of type T (*)(T6) o names a function that receives a reference to an object of type Te and returns the address of a region that holds an object of type T d. All of the above e. None of the above 4. Code 1.0 // decltype with templates // deeltype.cpp 1. #include decltype (t + u) ( return t + u;) 4. int main() { int i 3 , 6: double x- 4.5; atd::cout // ascending order comparison template bool ascending (Ta, Tb) (return a > b: ) // descending order comparison template bool descending (T a, Tb) { return a void sort(T* a, int n, bool (*comp) (T, T)) { for (int i -n- 1; i > 0; i--) { for (int j = 0; j void display (T* a, int n) { for (int i 0; i // order options enum class Order (ascending, descending); // order comparison template class Compare Order order; public: Compare (Order o) ! order (o) () bool operator () (T6 a, T. b) const { return order - Order:: ascending ? a > b a b ; comp) // bubble sort template void sort (T. a, int n, const Compare for (int i-n- 1; i > 0; i--) { for (int j = 0; j void display (T* a, int n) for (int i = 0; i (Order: ascending) ) display (a, n): sort(a, n, Comparecint> (Order:descending)): display (a, n): Answer Questions 11 using Code 4.0 11.
