Technical Interview Questions

1. Q: What is the difference between C and C++?
   Ans: C is a procedural programming language that focuses on functions and structured programming, while C++ is an object-oriented programming language that introduces concepts like classes, objects, inheritance, and polymorphism. C++ is essentially an extension of C, with additional features for object-oriented design. C is often used for system-level programming, whereas C++ is preferred for applications requiring complex data structures and reusable code.

2. Q: Explain the concept of OOPs.
   Ans: OOPs (Object-Oriented Programming) is a programming paradigm that organizes software design around objects rather than functions and logic. It is based on four key principles:

   • Encapsulation: bundling data and methods.

   • Inheritance: creating new classes from existing ones.

   • Polymorphism: using a single interface for different data types.

   • Abstraction: hiding complex details and showing only essential features.
     OOPs makes code more modular, reusable, and easier to maintain.

3. Q: What is a pointer in C?
   Ans: A pointer in C is a variable that stores the memory address of another variable. It allows direct access to memory locations, enabling dynamic memory allocation, efficient array handling, and manipulation of complex data structures like linked lists and trees. Pointers are powerful but require careful handling to avoid issues like memory leaks or segmentation faults.

4. Q: What is the difference between SQL and NoSQL?
   Ans: SQL databases are relational, table-based databases that use structured query language (SQL) for defining and manipulating data. They are ideal for complex queries and transactions. NoSQL databases, on the other hand, are non-relational and can store data in various formats like key-value pairs, documents, or graphs. NoSQL is more scalable and flexible, making it suitable for handling large volumes of unstructured data.

5. Q: What is the difference between stack and queue?
   Ans: A stack is a linear data structure that follows the LIFO (Last In, First Out) principle, meaning the last element added is the first one to be removed. It is commonly used in scenarios like function call stacks. A queue, on the other hand, follows the FIFO (First In, First Out) principle, where the first element added is the first one to be removed. Queues are often used in scheduling and buffering applications.

6. Q: What is the difference between Java and JavaScript?
   Ans: Java is a statically typed, object-oriented programming language primarily used for backend development, mobile apps (Android), and enterprise-level applications. JavaScript, on the other hand, is a dynamically typed scripting language used for front-end web development to create interactive and dynamic web pages. While both have similar names, they serve entirely different purposes and are used in different contexts.

7. Q: What is a constructor in Java?
   Ans: A constructor in Java is a special method used to initialize objects. It has the same name as the class and does not have a return type. Constructors are called automatically when an object is created and are used to set initial values for object attributes. There are two types of constructors: default constructors (no arguments) and parameterized constructors (with arguments).

8. Q: What is the difference between ArrayList and LinkedList in Java?
   Ans: ArrayList is a resizable array implementation of the List interface, providing fast random access but slower insertions and deletions due to shifting of elements. LinkedList, on the other hand, is a doubly-linked list implementation, offering faster insertions and deletions but slower random access. ArrayList is better for scenarios with frequent read operations, while LinkedList is preferred for frequent modifications.

9. Q: What is the difference between HTTP and HTTPS?
   Ans: HTTP (Hypertext Transfer Protocol) is an unsecured protocol used for transmitting data over the web, while HTTPS (Hypertext Transfer Protocol Secure) is a secure version that uses SSL/TLS encryption to protect data during transmission. HTTPS ensures data integrity, authentication, and confidentiality, making it essential for secure transactions like online banking or e-commerce.

10. Q: What is a deadlock in operating systems?
    Ans: A deadlock is a situation in which two or more processes are unable to proceed because each is waiting for the other to release a resource. It occurs when four conditions are met: mutual exclusion, hold and wait, no preemption, and circular wait. Deadlocks can be prevented by avoiding these conditions or resolved using techniques like resource allocation graphs or timeouts.

11. Q: What is normalization in databases?
    Ans: Normalization is the process of organizing data in a database to reduce redundancy and improve data integrity. It involves dividing large tables into smaller, related tables and defining relationships between them using primary and foreign keys. The main normal forms are 1NF, 2NF, 3NF, and BCNF, each addressing specific types of redundancy and dependency issues.

12. Q: What is the difference between primary key and foreign key?
    Ans: A primary key is a unique identifier for a record in a table, ensuring that no two rows have the same value. A foreign key, on the other hand, is a field in one table that references the primary key of another table, establishing a relationship between the two tables. While a primary key ensures uniqueness within a table, a foreign key ensures referential integrity between tables.

13. Q: What is the difference between abstraction and encapsulation?
    Ans: Abstraction focuses on hiding the implementation details and showing only the essential features of an object, making it easier to understand and use. Encapsulation, on the other hand, binds the data and methods into a single unit (class) and restricts access to the data using access modifiers like private, public, or protected. Abstraction simplifies complexity, while encapsulation ensures data security.

14. Q: What is the difference between process and thread?
    Ans: A process is an independent program in execution with its own memory space, while a thread is a subset of a process that shares the same memory space. Processes are heavier and require more resources, whereas threads are lighter and allow concurrent execution within a process. Threads are used to improve performance by enabling parallel execution of tasks.

15. Q: What is the difference between black-box testing and white-box testing?
    Ans: Black-box testing focuses on the functionality of the software without knowing the internal code structure. It is performed from the user's perspective to ensure the software meets requirements. White-box testing, on the other hand, involves testing the internal structure, design, and code of the software. It is performed by developers to ensure code quality and logic correctness.
