Algorithm and Code for Finding the Average of Four Numbers

Understanding the process of finding the average of four numbers is an essential skill in both programming and data analysis. This guide will explore the algorithmic approach to accomplish this task, alongside providing example code in both Python and Java. The objective is to provide a clear, concise, and beginner-friendly explanation for computing the average.

Understanding the Algorithm

When we talk about the average (or mean) of four numbers, we are essentially performing the following steps:

Gather Input: Collect four numerical values. These numbers can be integers or floating-point numbers, depending on the context. Sum the Numbers: Add the four numbers together to get the total sum. Divide by Four: Divide the total sum by 4 to get the average. Display the Result: Output the calculated average to the user.

Python Implementation

Python is a high-level programming language that is widely used for beginners due to its simplicity and readability. Here is a simple Python program to find the average of four numbers.

s  0for i in range(4):
    print("Enter number", i 1, end": ")  # Prompt the user to enter the number
    n  float(input())  # Take input as a floating-point number
    s   n  # Sum the number
print(f"Average  {s/4}")  # Display the calculated average

This program uses a for loop to iterate 4 times, prompting the user to enter each number and adding it to the total sum. Finally, it prints the average.

Alternative Python Implementation

Here is another way to achieve the same using a while loop:

s  0i  1while i 

Java Implementation

Java is a popular and versatile programming language, suitable for more complex applications. Here is a simple Java program to find the average of four numbers.

import ;public class Main {    public static void main(String[] args) {        float s  0;        Scanner sc  new Scanner();        for(int i  1; i 

This Java program uses a for loop to iterate 4 times, prompting the user to enter each number and adding it to the total sum. Finally, it prints the average.

Alternative Java Implementation

Here is another way to achieve the same using a while loop:

import ;public class Main {    public static void main(String[] args) {        float s  0;        Scanner sc  new Scanner();        int i  1;        while(i 

This Java program uses a while loop to achieve the same goal, iterating 4 times and prompting the user to enter each number, summing them, and displaying the average.

Both Python and Java programs follow the same logic: they gather four numbers, sum them, and divide the sum by 4 to find the average. The choice of language depends on the specific requirements and familiarity with the programming language.

Conclusion

By understanding and implementing the algorithm for finding the average of four numbers, you can solve this problem in different programming environments. Python and Java provide straightforward implementations to achieve this, making it easy to apply similar logic in more complex scenarios.
