Regression is the process of retesting a software application to ensure that changes or fixes have not introduced new defects.
Regression testing is performed to validate that previously working functionality is still intact after making changes to the software.
It involves rerunning test cases that have been previously executed to ensure that no new bugs have been introduced.
Regression testing is typically automated to ...
A friend function is a non-member function that has access to the private and protected members of a class.
Declared inside the class but defined outside the class scope
Can access private and protected members of the class
Not a member of the class but has access to its private members
Used to allow external functions to access and modify private data of a class
Can be declared as a friend in another class
atoi function converts a string to an integer in C.
The function takes a string as input and returns an integer.
Leading white spaces are ignored.
If the string contains non-numeric characters, the function stops conversion and returns the converted value.
The function returns 0 if the input string is not a valid integer.
Example: atoi('123') returns 123.
A program to print star pattern
Use nested loops to print the pattern
The outer loop controls the number of rows
The inner loop controls the number of stars to be printed in each row
Use print() or println() function to print the stars
Run time polymorphism is the ability of a program to determine the object type at runtime and call the appropriate method.
It is achieved through virtual functions and dynamic binding.
Allows for more flexible and extensible code.
Example: a base class Animal with virtual function makeSound() and derived classes Dog and Cat that override makeSound().
At runtime, if an Animal pointer points to a Dog object, calling makeSoun
Right outer join is a type of join operation that returns all the rows from the right table and the matching rows from the left table.
Right outer join is denoted by the RIGHT JOIN keyword in SQL.
It is used to combine rows from two tables based on a related column.
In the result set, unmatched rows from the right table will have NULL values for the columns of the left table.
A real-world scenario for using a right outer j...
Refrential integrity ensures that relationships between tables in a database remain consistent.
It is a database concept that ensures that foreign key values in one table match the primary key values in another table.
It prevents orphaned records in a database.
It maintains data consistency and accuracy.
For example, if a customer record is deleted, all related orders for that customer should also be deleted.
It is enforced...
Primary key uniquely identifies a record in a table, while Unique key ensures uniqueness of a column.
Primary key can't have null values, Unique key can have one null value
A table can have only one Primary key, but multiple Unique keys
Primary key is automatically indexed, Unique key is not necessarily indexed
Triggers are database objects that are automatically executed in response to certain events.
Triggers can be used to enforce business rules, audit changes, or replicate data.
There are two types of triggers: DML triggers and DDL triggers.
DML triggers are fired in response to DML statements (INSERT, UPDATE, DELETE).
DDL triggers are fired in response to DDL statements (CREATE, ALTER, DROP).

Inheritance is a concept in object-oriented programming where a class inherits properties and behaviors from another class.
Inheritance allows for code reuse and promotes modularity.
The class that is being inherited from is called the superclass or base class.
The class that inherits from the superclass is called the subclass or derived class.
The subclass can access the public and protected members of the superclass.
Inhe...
Regular expressions in PHP are powerful tools for pattern matching and manipulating strings.
Regular expressions are defined using the preg_match() function in PHP.
They are used to search, replace, and validate strings based on specific patterns.
Regex patterns consist of a combination of characters and special symbols.
Modifiers can be added to the pattern to control the matching behavior.
Common regex functions in PHP in...
Polymorphism is the ability of an object to take on many forms. It allows objects of different classes to be treated as the same type.
Polymorphism allows a single interface to be used for different types of objects.
It enables code reusability and flexibility in object-oriented programming.
For example, a parent class 'Animal' can have multiple child classes like 'Dog', 'Cat', and 'Bird'. They can all be treated as 'Anim...

The code for finding the Lowest Common Ancestor (LCA) in a Binary Search Tree (BST).
Start from the root node and compare it with the given two nodes.
If both nodes are smaller than the current node, move to the left subtree.
If both nodes are greater than the current node, move to the right subtree.
If one node is smaller and the other is greater, then the current node is the LCA.
Continue this process until the LCA is fou
A DBMS for managing college faculty, professors, courses, and students.
The DBMS should have tables for faculty, professors, courses, and students.
Each table should have appropriate attributes to store relevant information.
Relationships can be established between tables using foreign keys.
Queries can be used to retrieve information about faculty, professors, courses, and students.
The DBMS can be used to track enrollment

HR round that lasted for 45 minutes. Did brainstorming on puzzles and HR asked questions to know more about me.
Tips : During HR, think before you speak, they can catch any word that you speak. Prepare well for aptitude, as they shortlist less people after the test. Ask good questions during the end of the interviews. It might impress them. So prepare for it before going for the interview. Lastly, don’t be nervous, HRs are only trying to make you nervous during the interview as a part of the stress test.
Tip 1 : Must do Previously asked Interview as well as Online Test Questions.
Tip 2 : Go through all the previous interview experiences from Codestudio and Leetcode.
Tip 3 : Do at-least 2 good projects and you must know every bit of them.
Tip 1 : Have at-least 2 good projects explained in short with all important points covered.
Tip 2 : Every skill must be mentioned.
Tip 3 : Focus on skills, projects and experiences more.
