A copy constructor is a special type of constructor that creates a new object as a copy of an existing object.
Copy constructor should have a parameter of the same class type
It is used to create a new object by copying the values of an existing object
It is called when a new object is created from an existing object
A virtual function is a member function that is declared within a base class and is redefined by a derived class.
Declare a virtual function in the base class using the 'virtual' keyword.
Override the virtual function in the derived class using the 'override' keyword.
Use the base class pointer to call the virtual function, which will be resolved at runtime based on the actual object type.
Oops concept refers to Object-Oriented Programming principles and their implementation in software development.
Oops concepts include inheritance, polymorphism, encapsulation, and abstraction.
Inheritance allows a class to inherit properties and behaviors from another class.
Polymorphism allows objects to be treated as instances of their parent class.
Encapsulation hides the internal state of an object and only exposes nec...

I applied via Job Portal and was interviewed in Oct 2024. There were 2 interview rounds.
They asked LRU implementation of data structure
Reflection API in Java allows for inspecting and modifying classes, methods, fields at runtime.
Reflection API provides a way to examine and modify the behavior of classes, methods, and fields at runtime.
It allows access to class information, such as constructors, methods, fields, annotations, etc.
Reflection can be used for dynamic loading of classes, invoking methods at runtime, and examining annotations.
Example: Using...

Reversing a linked list involves changing the direction of pointers to go from the end to the beginning.
Start by initializing three pointers: current, previous, and next.
Iterate through the linked list, updating the pointers to reverse the direction of the links.
Update the head of the linked list to point to the new first node, which was the original last node.
Program to find perfect squares between two numbers
Iterate through numbers between the given range
Check if the square root of the number is an integer
If yes, then it is a perfect square
Smart pointers in C++ are objects that act like pointers but provide automatic memory management.
Smart pointers help prevent memory leaks by automatically managing memory allocation and deallocation.
Examples include unique_ptr, shared_ptr, and weak_ptr.
unique_ptr is used for exclusive ownership, shared_ptr for shared ownership, and weak_ptr to prevent circular references.
Mutual exclusion is a concept in concurrent programming where only one thread can access a shared resource at a time.
Ensures that only one thread can access a critical section of code at a time
Prevents race conditions and data corruption
Commonly implemented using locks, semaphores, or mutexes
Example: Using a mutex to protect a shared variable in a multi-threaded application
Implementing multithreading involves creating and managing multiple threads to execute tasks concurrently.
Identify the tasks that can be executed concurrently
Create and manage multiple threads to execute these tasks simultaneously
Use synchronization techniques like locks and semaphores to prevent race conditions
Handle communication and coordination between threads
Consider thread safety and resource sharing issues
