Given the following class: class Monkey{ string name; int age; public: void setName(string n){ name = n; } } How can you change the name for a Monkey mon object to "Sir Monkey"?

monkeymon.setName("Sir Monkey");

What is inheritance in C++?

Inheritance in C++ allows a class to inherit properties and behaviors from another class.

Inheritance in C++ is used to create new classes based on existing classes

Inheritance in C++ is limited to inheriting only data members from another class

Inheritance in C++ is not supported in object-oriented programming

What is the syntax for inheriting a class in C++?

class DerivedClass : accessSpecifier BaseClass {}

class DerivedClass :: BaseClass {}

class DerivedClass : public BaseClass {}

class DerivedClass : BaseClass {}

What is the difference between public, private, and protected inheritance in C++?

Public inheritance makes the public members of the base class accessible in the derived class, private inheritance makes the public and protected members of the base class private in the derived class, and protected inheritance makes the public and protected members of the base class protected in the derived class.

Protected inheritance makes the private members of the base class protected in the derived class

Private inheritance makes the public members of the base class private in the derived class

Public inheritance makes the private members of the base class accessible in the derived class

Explain the concept of virtual inheritance in C++.

Virtual inheritance in C++ is used to resolve the ambiguity that arises when a class is derived from multiple classes that have a common base class. It ensures that only one instance of the common base class is inherited by the derived class.

Virtual inheritance in C++ is used to allow multiple instances of the common base class to be inherited by the derived class

Virtual inheritance in C++ is used to prevent a class from being inherited by any other class

Virtual inheritance in C++ is used to create instances of classes that are not physically present in memory

What are the different types of polymorphism in C++? Explain with examples.

Compile-time polymorphism and runtime polymorphism. Compile-time polymorphism is achieved through function overloading and operator overloading, while runtime polymorphism is achieved through virtual functions and function overriding.

Single polymorphism and multiple polymorphism. Single polymorphism is achieved through function overloading and multiple polymorphism is achieved through operator overloading.

Static polymorphism and dynamic polymorphism. Static polymorphism is achieved through virtual functions and dynamic polymorphism is achieved through function overloading.

Simple polymorphism and complex polymorphism. Simple polymorphism is achieved through operator overloading and complex polymorphism is achieved through function overloading.

What is encapsulation in C++?

The process of bundling related data members and functions together in a single class

A way to create multiple classes

A function that modifies variables

A mechanism for defining constants

Which of the following is an advantage of encapsulation?

It makes code cleaner and easier to read by grouping related data and functions

It allows variables to be accessed from any class

It forces all data members to be public

It removes the need for constructors

What is the difference between encapsulation and data hiding?

Encapsulation is about grouping related code, while data hiding restricts access to certain members

Data hiding is the same as encapsulation

Encapsulation always requires data hiding

Encapsulation hides implementation details, but data hiding allows full access to class members

What is the primary purpose of setter functions in C++?

To modify private data members from outside the class

To allow read-only access to private data members

To perform calculations on variables

What is the purpose of getter functions in C++?

To return the values of private data members

How does encapsulation help with modifying data members in a controlled way?

By using getter and setter functions to control how data members are accessed or modified

By providing direct access to variables

By allowing all functions to modify variables directly

By creating multiple copies of data members

What happens if you try to access a private data member directly from outside the class?

The program raises a compile-time error

The variable is automatically converted to public

The variable is accessed without restriction

What does modularity means?

Subdividing programs into small independent parts

Wrapping things into single unit?

Both procedural & object oriented programming language

Procedural programming language

Functional programming language

Which of the following explains Polymorphism?

int func(float); int func(int, int, char);

int func(int, int); float func1(float, float);

What will be the output of this piece of code?

print derived class show base class

print derived class show derived class

Which of the following is invalid prototype for function overloading

(B) void fun (int x); void fun (int y);

(A) void fun (int x); void fun (char ch) ;

(C) void fun (double d); void fun (char ch);

(D) void fun (double d); void fun (int y);

What is a template in C++?

A template in C++ is a blueprint for creating functions or classes that can work with any data type.

A template in C++ is a type of variable.

A template in C++ is a specific instance of a class.

A template in C++ is a function that only accepts integers.

How do function templates differ from class templates?

Function templates are for functions, class templates are for classes.

Function templates require a specific return type, class templates do not.

Class templates are for functions, while function templates are for classes.

Function templates can only be used with integers.

What are the advantages of using templates in C++?

Code reusability, type safety, reduced code duplication, and improved performance.

Limited compatibility with data types

What is meant by the template parameter?

It can be used to pass a type as an argument

It can be used to evaluate a type

It can be used to delete a type

Pick out the correct statement.

you only need to write one function, and it will work with many different types

it will take a long time to execute

it will take a long time to execute & duplicate code is increased
