Functions in C | Power of a Num (a^b) | With Parameters and With Return Value | 100 Programs in C
Welcome to the 100 Programs in C Series 🚀
In this video, we’ll solve a classic and important problem — finding the Power of a Number (a^b) using a Type-4 Function in C — a function that has parameters and a return value.
This is one of the most common function types you’ll use in real-world programming and interviews.
We’ll pass two inputs — the base and the exponent — and return the result to the calling function (main()).
🎯 What You’ll Learn
Concept of Type-4 Functions in C (With Parameters and With Return Value)
How to pass multiple values to a function
How the return statement sends data back to main()
Step-by-step dry run of the power() function
Real-time output and logic breakdown
Learning Outcome
By the end of this video, you’ll:
✅ Understand how parameters and return values work together.
✅ Know how to pass data to a function and get a result back.
✅ Be confident writing modular, reusable code in C.
