Week 9

Question 1

Naming a file or a variable is the first and the very basic step that a programmer takes to write clean codes, where naming has to be appropriate so that for any other programmer it acts as an easy way to read the code. In C++, naming conventions are the set of rules for choosing the valid name for a variable and function in a C++ program.

Answer 1

Naming Convention

Question 2

Advantages of naming Conventions

Answer 2

*Avoids naming conflicts.
*Improves clarity of the code in case of ambiguity.
*Helps to formalize and promote consistency within a team.
*Improves understanding and readability of the code.

Question 3

This is a style where words within a name are capitalized, except the first word.

Answer 3

Camel Case

Question 4

also known as Upper Camel Case): This is a style where each word in a name begins with a capital letter, including the first word.

Answer 4

Pascal Case

Question 5

(also known as Lowercase with underscores): This is a style where words within a name are separated by underscores and all letters are lowercase.

Answer 5

Snake Case

Question 6

is a variation of snake_case, where all letters are uppercase and words are separated by underscores (_).

Answer 6

Screaming Case

Question 7

pointers is a pointer to the current instance of a class. It is used to refer to the object within its own member functions.

Answer 7

This -> Notation

Question 8

is an implicit pointer available within non-static member functions of a class or structure. It points to the current object instance, letting the object access its own member variables and functions.

Answer 8

This -> Notation

Question 9

pointer can also be used as a constructor, a special member function that is called when an object of the class is created.

Answer 9

This -> Notation

Question 10

pointer is used to refer to the object that is being created.

Answer 10

This -> Notation

Question 11

The capability of a class to derive properties and characteristics from another class is called _________

Answer 11

Inheritance

Question 12

is one of the most important features of Object Oriented Programming in C++

Answer 12

Inheritance

Question 13

It allows us to create a new class (derived class) from an existing class (base class). The derived class inherits the features from the base class and can have additional features of its own.

Answer 13

Inheritance

Question 14

if we derive a subclass from a public base class. Then the public member of the base class will become public in the derived class and protected members of the base class will become protected in the derived class.

Answer 14

Public Inheritance Mode

Question 15

If we derive a subclass from a Protected base class. Then both public members and protected members of the base class will become protected in the derived class.

Answer 15

Protected Inheritance Mode

Question 16

If we derive a subclass from a Private base class. Then both public members and protected members of the base class will become private in the derived class. They can only be accessed by the member functions of the derived class.

Answer 16

Private Inheritance Mode

Question 17

a class is allowed to inherit from only one class. i.e. one base class is inherited by one derived class only.

Answer 17

Single Inheritance

Question 18

is a feature of C++ where a class can inherit from more than one class. i.e one subclass is inherited from more than one base class.

Answer 18

Multiple Inheritance

Question 19

In this type of inheritance, a derived class is created from another derived class and that derived class can be derived from a base class or any other derived class. There can be any number of levels.’

Answer 19

Multilevel Inheritance
