πŸ™‹ Introduction

In the world of programming, dealing with numerical data and performing calculations is a fundamental skill. One common task is finding the average of a set of numbers. This is a basic operation used in various applications, ranging from statistical analysis to data processing.

In this tutorial, we will explore a C program designed to find the average of N numbers. The program takes a user-specified number of inputs, calculates their sum, and then computes the average.

πŸ“„ Example

Let's delve into the C code that accomplishes this task.

findAverage.c
Copied
Copy To Clipboard
#include <stdio.h>

// Function to find the average of N numbers
double findAverage(int n) {
  double sum = 0, number;

  // Input N numbers from the user
  printf("Enter %d numbers:\n", n);

  for (int i = 0; i < n; ++i) {
    scanf("%lf", & number);
    sum += number;
  }

  // Calculate the average
  double average = sum / n;
  return average;
}

// Driver program
int main() {
  // Replace this value with your desired number of inputs (N)
  int n = 5;

  // Call the function to find the average
  double result = findAverage(n);

  // Display the result
  printf("The average of the entered numbers is: %lf\n", result);

  return 0;
}

πŸ’» Testing the Program

To test the program with different numbers, modify the value of n in the main function.

Output
Enter 5 numbers:
1 2 3 4 5 
The average of the entered numbers is: 3.000000

🧠 How the Program Works

  1. The program defines a function findAverage that takes an integer n as input, prompts the user to input n numbers, calculates their sum, and then computes and returns the average.
  2. Inside the main function, replace the value of n with your desired number of inputs.
  3. The program calls the findAverage function, and the result is displayed.

🧐 Understanding the Concept to find Average of N Numbers

Before delving into the code, let's understand the concept behind finding the average of N numbers. The program uses a loop to input N numbers, calculates their sum, and then divides the sum by N to find the average.

For example, if the user enters 5 numbers (10, 15, 20, 25, 30), the program calculates (10 + 15 + 20 + 25 + 30) / 5, resulting in an average of 20.

🎒 Optimizing the Program

While the provided program is effective, consider exploring and implementing error handling for input validation to enhance the program's robustness.

Feel free to incorporate and modify this code as needed for your specific use case. Happy coding!
