Reverse a Number in C Programming | While Loop Logic (Marathi)

In this video, we write a C program to accept a number from the user and print its Reverse (e.g., Input: 123 → Output: 321). 💻 We use the Digit Separation Logic inside a while loop: Extract Last Digit: rem = num % 10 Build Reverse Number: rev = (rev * 10) + rem Reduce Number: num = num / 10 We also explain why initializing rev = 0 is important to avoid garbage values. 📝 Topics Covered: ✅ Logic to reverse any integer. ✅ The formula: rev * 10 + rem. ✅ Dry run of the code with input 123. ✅ Compiling and running the code. 👨‍💻 This video is perfect for: Beginners learning While Loops and Modulo Operator. Students preparing for "Palindrome Number" logic (This is the first step!). BCS/BCA/Engineering practical preparations. 🚀 Why learn from NR Classes? We focus on Logic Building, not just syntax. Our goal is to make you confident in writing your own programs. 📞 Join Our Offline/Online Classes: Want to learn personally from experts?
