Yes, I prefer coding in C and have read The C Programming Language book. I have also explored the concept of Inheritance in C.
I find C to be a powerful and efficient language for system programming.
Yes, I have read The C Programming Language book by Dennis Retchie and found it to be a great resource.
Recently, I have been exploring the concept of Inheritance in C through various online resources and tutorials.
While C do...
Inheritance allows a class to inherit properties and methods from another class.
Inheritance promotes code reusability and saves time and effort in programming.
It allows for the creation of a hierarchy of classes with shared characteristics.
For example, a class Animal can be inherited by classes such as Dog, Cat, and Bird, which share common properties and methods.
Inheritance can be implemented using the 'extends' keywo
Liskov substitution principle is a principle in object-oriented programming that states that objects of a superclass should be able to be replaced with objects of its subclasses without affecting the correctness of the program.
Subtypes must be substitutable for their base types
Derived classes must not change the behavior of the base class
Violating the principle can lead to unexpected behavior and errors
Example: A squar...
Explanation of OOPs concepts with programs
Encapsulation: Wrapping data and functions into a single unit. Example: Class in Java
Abstraction: Hiding implementation details and showing only necessary information. Example: Abstract class in C#
Inheritance: Acquiring properties and behavior of a parent class. Example: Child class extending parent class in Python
Polymorphism: Ability of an object to take many forms. Example:
Dynamic polymorphism is achieved through virtual functions and inheritance in object-oriented programming.
Create a base class with virtual functions
Create derived classes that override the virtual functions
Use pointers or references of the base class to call the virtual functions
The appropriate derived class function will be called based on the object being pointed to or referred to
Global variables can lead to unexpected changes and make debugging difficult.
Global variables can be accessed and modified from any part of the code, making it difficult to track changes.
They can cause naming conflicts if multiple variables with the same name are used in different parts of the code.
Using global variables can make it harder to test and debug code, as it can be difficult to isolate the cause of errors.
Th...
Using 'goto' can make code hard to read, maintain and debug.
Goto statements can create spaghetti code that is difficult to follow.
It can make it harder to understand the flow of the program.
It can also make debugging more difficult.
There are usually better alternatives to using goto, such as using loops or functions.
Some programming languages, such as Java and Python, do not even have a goto statement.
Using goto can al...
My favorite subject is history because it helps me understand the present and learn from the past.

Implicit objects are pre-defined objects in JSP that can be accessed without being explicitly declared.
Implicit objects are created by the JSP container during the translation phase.
They can be accessed using predefined names such as request, response, session, application, out, pageContext, config, and exception.
For example, the request object can be used to retrieve parameters from a form or URL.
The session object ca...

Floyd-Warshall's algorithm is used to find the shortest path between all pairs of vertices in a weighted graph.
Create a 2D array to store the distances between all pairs of vertices.
Initialize the array with the weights of the edges in the graph.

If not, add the current element to the hash table
Indexing is a technique used in DBMS to improve the performance of queries.
Indexing creates a separate data structure that allows faster retrieval of data.
It works by creating a pointer to the location of data in the table.
Indexes can be created on one or more columns of a table.
Types of indexing include B-tree, hash, and bitmap indexing.
Indexes can also be clustered or non-clustered.
Clustered indexes determine the phy...
B and B+ trees are data structures used for efficient searching and sorting of large datasets.
B trees are balanced trees used for disk-based storage systems.
B+ trees are similar to B trees but have all data stored in the leaf nodes for faster searching.
B trees have a variable number of keys per node, while B+ trees have a fixed number.
B trees have a higher fanout than B+ trees, making them more efficient for smaller da...
Program to find lowest common ancestor of two nodes in binary search tree and binary tree with brute force approach.
For binary search tree, traverse from root to both nodes and store the path. Then compare paths to find LCA.
For binary tree, traverse from root to both nodes and store the path. Then compare paths to find LCA.
Brute force approach involves checking each node's descendants to see if they contain both nodes.
