Zero Days Code - Invidious

Zero Days Code

I am a 8th-semester Computer Science student at the University of Liberal Arts Bangladesh (ULAB), and I create easy-to-understand Bangla tutorials on important and often difficult topics from the CSE curriculum.
My goal is to help students learn complex concepts in a simple way through long, detailed, and beginner-friendly explanations.

On this channel, you will find tutorials on:
C programming
SQL and database concepts
HTML & CSS
Problem-solving and coding fundamentals
University-level computer science topics
Whether you are a beginner, intermediate learner, or preparing for exams, these lessons will help you build strong foundations in programming and computer science.

If you want clear explanations, in Bangla, with real examples and step-by-step guidance, this channel is for you.
Subscribe and start learning with me!
