4.2 – Functions in C (Type 1) | 3 Important Programs Explained | C Programming – New Series

Welcome to C Programming – Complete Course (New Series) by Burle Sharma. In this class (4.2), we continue with user-defined functions (Type 1) where: ✔ All input, processing, and output are written inside the function ✔ The function is called from main() To strengthen this concept, we solve three important programs step by step. 📌 Programs Covered in This Video ✔ Accept a 3-digit number and display the last digit ✔ Accept a number and check whether it is Even or Odd ✔ Accept a number and check whether it is Prime or Composite 📌 Structured Approach Followed 👉 Writing the expected output 👉 Writing the function with logic 👉 Calling the function from main() 👉 Performing detailed dry run 👉 Executing the program and verifying output 📌 Concepts Explained in This Video 🔹 Applying function (Type 1) in real programs 🔹 Writing logic inside function body 🔹 Calling function from main() 🔹 Using previously learned number logic 🔹 Understanding program flow Students clearly understand: 🟢 How functions execute step by step 🟢 How logic is placed inside function 🟢 How main() transfers control to function 🟢 How output is generated from function 📌 Special Note These three programs are very important because: 👉 They will be reused in the remaining 3 types of functions 👉 This helps students compare and understand all function types clearly 🎓 What You’ll Learn in This Video 🟢 Writing programs using functions (Type 1) 🟢 Applying number logic inside functions 🟢 Understanding function calling 🟢 Performing structured dry run 🟢 Strengthening programming fundamentals 🧠 Key Learning Point Practicing the same programs in different function types helps students: ✔ Understand differences clearly ✔ Build strong conceptual clarity ✔ Improve coding confidence 📌 Next Class Update 👉 In upcoming classes, we will solve the same programs using other types of functions for better comparison and understanding. #CProgramming #LearnC #BurleSharma #CProgrammingNewSeries #FunctionsInC #UserDefinedFunction #EvenOddInC #PrimeNumberInC #ProgrammingPractice#geecoding
