Given : integer x = 40, y = 35, z = 20, w = 10. Comment about the output of the following two statements:
print x * y / z – w
print x * y / (z – w) ?

A. Differ by 80

B. Same

C. Differ by 50

D. Differ by 160

Answer : A. Differ by 80

Explanation :

print x * y / z – w = 40 * 35 / 20 – 10 = 60
print x * y / (z – w) = 40 * 35 / ( 20 – 10 ) = 140
Difference is 80

I have a problem to solve that takes n as an input number. The problem has a property that given the solution for (n-1), I can easily solve the problem for n. Which programming technique will I use to solve such a problem ?

A. Iteration

B. Decision-making

C. Object Oriented Programming

D. Recursion

Answer : D. Recursion

Explanation

Recursion(the repeated application of a recursive procedure) solve the problem has a property that given the solution for (n-1).

Which of the following cannot be inherited ?

A. Friend

B. Static

C. Destructor

D. Constructor

Answer : C. Destructor

Explanation :

  • Friend Class – A friend class can access private and protected members of other class in which it is declared as friend. It is sometimes useful to allow a particular class to access private members of other class.
  • Constructor – A constructor is a member function of a class which initializes objects of a class. In C++, Constructor is automatically called when object (instance of class) create. It is special member function of the class.
  • Static – Static categories are sealed and thus can’t be transmissible. They can not inherit from any category except Object. Static categories cannot contain associate instance constructor. but, they will have a static builder.
  • Destructor – Destructor is a member function which destructs or deletes an object.
