Coding Interview Questions with Answers Part-4 ๐ง ๐ป
31. What is a pointer
A pointer stores the memory address of a variable.
- Direct memory access
- Efficient data handling
Used in C/C++, dynamic memory allocation.
32. Difference between pointer and reference
Pointer: holds address, can be null, can change target.
Reference: alias of variable, cannot be null, cannot change binding.
Pointer is flexible, reference is safer.
33. What is a memory leak
Memory leak: memory not released.
- Program slows down
- App crashes
Causes: missing free/delete, unclosed resources.
Use garbage collection or smart pointers.
34. What is segmentation fault
Segmentation fault: invalid memory access.
- Access null pointer
- Array index overflow
Seen in C/C++. Check pointer usage.
35. Difference between process and thread
Process: independent, own memory, heavier.
Thread: part of process, shared memory, lightweight.
Threads share resources.
36. What is multithreading
Multithreading: runs tasks in parallel.
- Better CPU use
- Faster execution
Examples: web servers, background tasks.
Risk: data inconsistency.
37. What is synchronization
Synchronization: controls shared data access.
Prevents race conditions. Use locks, mutex, semaphores.
Safety over speed.
38. What is deadlock
Deadlock: threads wait forever.
- Thread A holds lock 1
- Thread B holds lock 2
Result: system freeze.
39. Conditions for deadlock
All four must exist:
- Mutual exclusion
- Hold and wait
- No preemption
- Circular wait
Break one to avoid deadlock.
40. Shallow copy vs deep copy
Shallow: copies reference, changes affect both.
Deep: copies data, fully independent.
Example: objects with nested data.

Coding Interview Questions with Answers Part-5 ๐ง ๐ป
41. What is exception handling
Exception handling manages runtime errors.
โข Prevents crashes
โข Keeps program running
Try-catch-finally blocks handle errors (e.g., divide by zero).
42. Checked vs unchecked exceptions
Checked: compile-time, must handle (e.g., IOException).
Unchecked: runtime, not forced (e.g., NullPointerException).
Checked equals predictable.
43. Mutable vs immutable object
Mutable: state changes (e.g., List).
Immutable: state fixed (e.g., String).
Immutability provides thread safety and easier debugging.
44. What is garbage collection
Garbage collection frees unused memory.
Tracks unreachable objects and deletes them (Java, Python).
Reduces memory leaks.
45. What is REST API
REST API enables client-server communication via HTTP methods (GET, POST, PUT, DELETE).
Stateless requests (e.g., fetch user data).
46. What is JSON
JSON: lightweight, readable data format.
Language-independent, used in API responses (key-value pairs).
47. HTTP vs HTTPS
HTTP: no encryption, less secure.
HTTPS: encrypted, protects user data.
48. What is version control? Why Git matters
Version control tracks code changes. Git enables collaboration, rollback, and branch management.
Used by all tech teams.
49. Explain a coding problem you optimized recently
State problem, bottleneck, optimization, and result (e.g., reduced nested loops, improved O(nยฒ) to O(n)).
50. How you approach a new coding problem
1. Understand problem
2. Clarify constraints
3. Brute force
4. Optimize
5. Test edge cases
Think aloud; interviewers watch process.

Top JavaScript Interview Questions & Answers ๐ปโจ
๐ 1. What is JavaScript and why is it important?
Answer: JavaScript is a dynamic, interpreted programming language that makes web pages interactive. It runs in browsers and on servers (Node.js), enabling features like animations, form validation, and API calls.
๐ 2. Explain the difference between var, let, and const.
Answer:
๐ 3. What are closures in JavaScript?
Answer: Closures occur when a function remembers and accesses variables from its outer scope even after that outer function has finished executing.
๐ 4. What is the Event Loop?
Answer: The Event Loop manages asynchronous callbacks by pulling tasks from the callback queue and executing them after the call stack is empty, enabling non-blocking code.
๐ 5. What are Promises and how do they help?
Answer: Promises represent the eventual completion or failure of an asynchronous operation, allowing cleaner async code with
๐ 6. Explain 'this' keyword in JavaScript.
Answer:
๐ 7. What is prototypal inheritance?
Answer: Objects inherit properties and methods from a prototype object, allowing reuse and shared behavior in JavaScript.

๐ 2. Explain the difference between var, let, and const.
Answer:
var has function scope and is hoisted; let and const have block scope. const defines constants and cannot be reassigned.๐ 3. What are closures in JavaScript?
Answer: Closures occur when a function remembers and accesses variables from its outer scope even after that outer function has finished executing.
๐ 4. What is the Event Loop?
Answer: The Event Loop manages asynchronous callbacks by pulling tasks from the callback queue and executing them after the call stack is empty, enabling non-blocking code.
๐ 5. What are Promises and how do they help?
Answer: Promises represent the eventual completion or failure of an asynchronous operation, allowing cleaner async code with
.then(), .catch(), and async/await.๐ 6. Explain 'this' keyword in JavaScript.
Answer:
this refers to the context object in which the current function is executed โ it varies in global, object, class, or arrow function contexts.๐ 7. What is prototypal inheritance?
Answer: Objects inherit properties and methods from a prototype object, allowing reuse and shared behavior in JavaScript.
๐ 8. Difference between == and === operators?
Answer:
== compares values after type coercion; === compares both value and type strictly.๐ 9. How do you handle errors in JavaScript?
Answer: Using
try...catch blocks for synchronous code and .catch() or try-catch with async/await for asynchronous errors.๐ ๐ What are modules in JavaScript and their benefits?
Answer: Modules split code into reusable files with
import and export. They improve maintainability and scope management.๐ก Pro Tip: Complement your answers with simple code snippets and real project scenarios wherever possible.

SQL Interview Questions with Answers
1. How to change a table name in SQL?
This is the command to change a table name in SQL:
ALTER TABLE table_name
RENAME TO new_table_name;
We will start off by giving the keywords ALTER TABLE, then we will follow it up by giving the original name of the table, after that, we will give in the keywords RENAME TO and finally, we will give the new table name.
2. How to use LIKE in SQL?
The LIKE operator checks if an attribute value matches a given string pattern. Here is an example of LIKE operator
SELECT * FROM employees WHERE first_name like โStevenโ;
With this command, we will be able to extract all the records where the first name is like โStevenโ.
3. If we drop a table, does it also drop related objects like constraints, indexes, columns, default, views and sorted procedures?
Yes, SQL server drops all related objects, which exists inside a table like constraints, indexes, columns, defaults etc. But dropping a table will not drop views and sorted procedures as they exist outside the table.
4. Explain SQL Constraints.
SQL Constraints are used to specify the rules of data type in a table. They can be specified while creating and altering the table. The following are the constraints in SQL: NOT NULL CHECK DEFAULT UNIQUE PRIMARY KEY FOREIGN KEY
