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;
        }

An inline function is a function that is expanded inline when invoked.ie. the compiler replaces the function call with the corresponding function code. An inline function is a function that is expanded in line when it is invoked. That is the compiler replaces the function call with the corresponding function code (similar to macro)

A reference variable provides an alias to a previously defined variable.

Data type & reference-name = variable name

All the above listed options are c++ tokens .They  include:

             - keywords

             - Identifiers

             - Constants

             - Strings

             - operators

The C++ programming technique allows defining user defined datatypes through structure. The

syntax to declare structure is as follows:

struct student

{

char name[100]

char address[250]

};

A function prototype is a declaration of a function that omits the function body. It specifies the function’s name, argument types and return type.

E.g. int add(int,int)

Stack. Because of its LIFO (Last In First Out) property it remembers its ‘caller’ so knows whom to return when the function has to return. Recursion makes use of system stack for storing the return addresses of the function calls. Every recursive function has its equivalent iterative (non-recursive) function. Even when such equivalent iterative procedures are written, explicit stack is to be used.

In C++, void represents the absence of type, so void pointers are pointers that point to a value that has no type. The void pointers can point to any data type.

You can declare void pointer as follows:

void *p;
