Title: Conquer University Exams & Coding Challenges: Essential Long-Answer & Programming Questions

Introduction:

Hello Problem Solvers! 👋

Welcome back to The KVR26, your partner for academic excellence and career advancement! I'm Kandula Vamshi Reddy. While knowing definitions is crucial (check out our Part A Questions post!), truly excelling in B.Tech semester exams and technical placements often requires applying concepts to solve problems, write code, and explain complex topics in detail.

Are you a B.Tech student striving to improve your SGPA/CGPA by mastering long-answer questions and programming tasks in subjects like C Programming Language? Are you preparing for technical interview rounds that involve writing code for tasks like matrix operations, file handling, or sorting algorithms?

This collection of "Part B" style questions, curated from past university papers, is designed precisely for that. It covers the core application-oriented aspects of the syllabus, pushing you to move beyond theory. These questions are relevant whether you're in CSE, IT, ECE, EEE, MECH, Civil, AI/ML, or any branch where programming fundamentals are tested.

The KVR26 aims to equip you with the resources needed to tackle these challenges confidently. Let's dive into these in-depth questions!

Essential Part B Questions (Topic-Wise):
