       int x;

       x integer


Reserve words cannot be used as a variable name.

       Zero


       One


       Two


       Three




Template functions can also be overloaded


       True

       False

       True

       False

When break statement is encountered in switch statement, it

       Stops the entire program

       Stops the execution of current statement

       Exits from switch statement

       None of the given options


We can also define a variable of user define data type (object) as static.

The declarator of Plus (+) member operator function is




       Class-Name  operator + (Class-Name  rhs)


       operator Class-Name + ( )


       operator Class-Name + ( rhs)


       Class-Name  operator + ( )



 Let suppose
    int a, b, c, d, e;
  a = b = c = d = e = 42;
This can be interpreted by the complier as:


       a = (b = (c = (d = (e = 42))));

       (a = b = (c = (d = (e = 42))));

       a = b = (c = (d = (e = 42)));

       (a = b) = (c = d) = (e = 42);

       addRecord(student[10]) ;



       addRecord(*student) ;

       True

       False


If a class A declares itself a friend of class B and a class B declares itself a friend of class C then



       Class A is also a friend of class C.

       Class B is also a friend of class A.

       Class A is also a friend of class C if A declares C as its friend.

       Class A is also a friend of class C if C declares A as its friend.

Overload the Binary Assignment (=) Operator.

Write a program which has a class List, This class should have Two data members, an array of integers list[] and an integer variable length (i.e. number of elements in the list).The class should further contain a default  constructor,  a Print() function which display the list and a Function insert() which insert an element in the list and  Assignment (= ) Operator function, which contain code for the assignment of one object to other. .

In main function define two objects list1 and list2 and use the statement list2 = list1; and use (call ) print function with both objects
