What is the output of this program ?

       #include
        using namespace std;
        int n(char, int);
        int (*p) (char, int) = n;
        int main()
        {
            (*p)('d', 9);
            p(10, 9);
            return 0;
        }
        int n(char c, int i)
        {
            cout << c <<  i;
            return 0;
        }

i.) Const - This variable means that if the memory is initialised once, it should not be altered by a program. 

ii.) Volatile - This variable means that the value in the memory location can be altered even though nothing in the program code modifies the contents. 

iii.) Mutable - This variable means that a particular member of a structure or class can be altered even if a particular structure variable, class, or class member function is constant.

Allocaters are implemented in C++ standard library but it is used for C++ template library.

Algorithm header file contain the supporting files needed for the execution of these functions.

A heap is a way to organize the elements of a range that allows for fast retrieval of the element.

To resolve all the side-effects in the program, the sequence point should not be overlapped.

It is a group of functions and implemented under algorithm header file.

There are four parameters. They are first1, last1, first2, predicate.
