PBA – 03 | Numbers and String Functions | Class 12 Computer Science | FBISE 2025
This video explains PBA Task 03, focused on implementing number-based and string-based functions in C++, as per the FBISE Class 12 Computer Science 2025 practical syllabus. You’ll learn how to create custom functions to work with numbers (e.g. even/odd, factorial, prime, sum of digits) and strings (e.g. length, reverse, palindrome, count vowels).
🎯 What’s Covered:
✅ Number functions: even/odd, factorial, prime check
✅ String functions: length, reverse, vowel count, palindrome
✅ Input/output demonstration
✅ Custom function definitions and calls in C++
✅ Aligned with FBISE PBA expectations for HSSC-II
📘 Ideal for Class 12 Computer Science students preparing for FBISE PBA 2025 and viva questions.
