Question Discussion & Solution

Inheritance

The capability of a class to derive properties from another class is called Inheritance

• The class that inherits properties from another class is called Subclass or Derived Class.
• The class whose properties are inherited by a subclass is called Base Class or Superclass.

Syntax for Inheritance

class derived_name : access_mode base_class

{

//body of derived class

};

Additional Information 

Polymorphism

Polymorphism is mainly divided into two types:

• Compile-time Polymorphism
• Runtime Polymorphism

Compile-time polymorphism

This is achieved by function overloading or operator overloading.

• Function Overloading - When there are multiple functions with the same name but different parameters then these functions are said to be overloaded
• Operator overloading - When there are multiple operations can be performed by using single operator is called operator overloading for example operator ‘+’ when placed between integer operands, adds them and when placed between string operands, concatenates them

Run Time Polymorphism

It is achieved by Function Overriding.

Conclusion

Feature of Reusability is followed by inheritance so the correct answer is the inheritance.

The correct answer is In 2004.

•  Darrah National Park was established in 2004.

Key Points

•  Darrah National Park ​
  • Mukundara Hills National Park is a national park in Rajasthan with an area of 759.99 km².
  • It was established in 2004 and consists of three wildlife sanctuaries: Darrah Wildlife Sanctuary, National Chambal Sanctuary, and Jawahar Sagar Wildlife Sanctuary.
  • It is located in the Kathiawar-Gir dry deciduous forests. 
  • 1955 – Darrah was declared a wildlife sanctuary.
  • 2004 – Declared as Mukundra Hills National Park.
  • 2013 – Got approval from NTCA & declared as Tiger Reserve.
  • 2020 – Moefcc notifies MHTR Eco-Sensitive Zone

​Additional Information

• About Rajasthan Wildlife
  • ​Rajasthan has Ranthambore National and Sariska National Park and Mukundara as a tiger reserve.
  • The UNESCO World Heritage Site Keoladeo National park along with Tal Chhapar, Van Vihar, and Jorbeed are for bird destinations in the state.
  • The Desert National Park is home to the critically endangered species of Great Indian Bustard.
  • Apart from these, Rajasthan is home to a large number of leopards, blackbuck, great Indian spotted eagle, and marsh crocodiles.

The correct answer is Jaisalmer and Bikaner.

Key Points
Tropical Thorn Forest:

• These forests are found in Jaisalmer, Bikaner and Barmer.
• It comprises 6.25% of the forest in Rajasthan. 
• Rainfall varies from 0 to 25 cm. It is scanty in nature.
• Xerophytic vegetation is found in this forest. 
• Khejri, Rohida, and Jaal are prominent trees present in the Forest.

Additional Information

The correct answer is Application Language.

• Application Language is the other name of functional language.

Key Points

• Functional languages have a mathematical style.
• A functional program is constructed by applying functions to arguments.
• Functional languages, such as LISP, ML, and Haskell, are used as research tools in language development, automated mathematical theorem provers, and in commercial projects.
• Other high-level languages are called functional languages.
• The best-known functional language of this type is LISP (List Processing).

Additional Information

• Machine code, also known as machine language, is the elemental language of computers.
  • It is read by the computer's central processing unit (CPU), is composed of digital binary numbers and looks like a very long sequence of zeros and ones.
  • Each CPU has its own specific machine language.
  • The processor reads and handles instructions, which tell the CPU to perform a simple task. Instructions are comprised of a certain number of bits.
• A high-level language is a programming language designed to simplify computer programming.
  • It is "high-level" since it is several steps removed from the actual code run on a computer's processor. 
  • High-level source code contains easy-to-read syntax that is later converted into a low-level language, which can be recognized and run by a specific CPU.
  • A compiler is a language translator that can convert high-level language programs into machine language in one go.
• An assembly language is a low-level programming language in which there is a very strong correspondence between the program's statements and the architecture's machine code instructions.

Concept:

System modelling is the process of developing abstract models of a system and each model presenting a different view or perspective of that system. 

Explanation:

Concept that has to be considered while modelling a new system are:

Abstraction: at highest level of abstraction, a solution is stated in broad terms while at the lowest level of abstraction a more detailed solution is provided.

Modularity: it is the single attribute of the software that allows a program to be individually manageable.

Information hiding in this algorithms and data contained within a module are inaccessible to to other modules.

Some other factors that are considered are: architecture, pattern, functional independence, refinement, refinement.
