Given a sentence as input, print all the unique combinations of two words in lexicographical order.Input

The input will be a single line containing a sentence.Output

The output should be multiple lines, each line containing the unique combination of two words in lexicographical order.Explanation

For example, if the given sentence is "raju plays cricket", the possible unique combination of two are (cricket, plays), (cricket, raju), (plays, raju). So the output should be

cricket plays
cricket raju
plays raju

Explain the type of inheritance with code.

Create two classes named Mammals and MarineAnimals. Create another class named BlueWhale 

which inherits both the above classes. Now, create a function in each of these classes which prints 

"I am mammal", "I am a marine animal" and "I belong to both the categories: Mammals as well as 

Marine Animals" respectively. Now, create an object for each of the above class and try calling

 function of Mammals by the object of Mammal

 function of BlueWhale by the object of BlueWhale

 function of each of its parent by the object of BlueWhale

 function of MarineAnimal by the object of MarineAnimal

Develop a C++ program to Subtract two complex number by overloading - operator using Friend function.

Create a class named 'Member' having the following members

1 data member

2 name

3 age

4 phone number

5 address

6 salary

It also has method named 'print salary' of the members. Two classes'employes ' & ' manager' inherits the 'member' classes . The 'employee' & 'manger' speclization and ' department ' respectively . Now, assign name , age , phone number, address & salary to an employer & a manger by making an object of both of these classes and print.

Write a program which has a class template for determining the largest and the smallest number

from a list of numbers. Use a constructor for input and appropriate data members and member

functions in support of your answer. [

Write a program which has an abstract class called Number having an integer data member.

The class contains a pure virtual function called operation. A class called Armstrong is derived from

class called Number. Another class called Palindrome is derived from class Number. Use

appropriate constructors and redefine the function called operation to display if the number is

Armstrong number as well as Palindrome in case it falls in this category. You may make use of

other data members and member functions if needed

Write a program which has a class called binary which has a character array to store a binary

string. The class decimal derives from class binary and contains an integer data member. Another

class called hexadecimal also derives from binary. Each class should contain constructors and

appropriate data members to input and display the elements. The display function of binary class

displays the binary equivalent, hexadecimal class’s display function displays hexadecimal

equivalent whereas decimal class’s display function displays the decimal equivalent.
