Question Discussion & Solution

• Multiple Inheritance in C++ is one in which a class can inherit members from more than one class
• A class who inherit the property is derived class and class from whom it is inherited is base class or parent class

Example:

class X //base class

{

public:

 X() { cout << "X's constructor" ; }

};

 class Y //base class

{

public:

 Y() { cout << "Y's constructor "; }

};

 class C: public B, public A // Derived class: Multiple inheritance

{

public:

 Z() { cout << "Z's constructor" ; }

Concept:

Polymorphism is a feature of OOPs that allows the object to behave differently in different conditions. 

Explanation:

In C++ we have two types of polymorphism:
1. Compile-time Polymorphism – This is also known as static (or early) binding.
2. Runtime Polymorphism – This is also known as dynamic (or late) binding.

Compile-time Polymorphism
Function overloading and Operator overloading are examples of Compile time polymorphism.

The pattern followed here is:

Hence, 119 is the next term in the series.

The pattern here is as follows:

Hence, JlL is the correct answer. 

The pattern followed here is:

25 → First digit of 23 and second digit of 65.

68 → First digit of 61 and second digit of 38.

? → First digit of 72 and second digit of 48 → 78.

Hence, the answer is 78.
