Enter 3 numbers from the user & make a function to print their average in java, c++, python, java.

Enter 3 numbers from the user & make a function to print their average.

To find the average of three numbers, you need to add the three numbers together and then divide the sum by three. Here's how you can write a function in C++, C, Python, and Java to take three numbers from the user and calculate their average:

JAVA

import java.util.*;

public class Solutions {

   public static void main(String args[]) {

      Scanner sc = new Scanner(System.in);

      int a = sc.nextInt();

      int b = sc.nextInt();

      int c = sc.nextInt();

 

      int average = (a + b + c) / 3;

      System.out.println(average);

   }   

}

 

C++:

// c++

#include <iostream>

using namespace std;

double average(double num1, double num2, double num3) {

    double sum = num1 + num2 + num3;

    double average = sum / 3;

    return average;

}

int main() {

    double num1, num2, num3;

    cout << "Enter three numbers: ";

    cin >> num1 >> num2 >> num3;

    double avg = average(num1, num2, num3);

    cout << "The average is: " << avg << endl;

    return 0;

}

This implementation takes three double numbers from the user using the cin function and then calls the average function to calculate their average. The average function calculates the sum of the three numbers and then divides the sum by 3 to get the average.

C:

// c

#include <stdio.h>

double average(double num1, double num2, double num3) {

    double sum = num1 + num2 + num3;

    double average = sum / 3;

    return average;

}

int main() {

    double num1, num2, num3;

    printf("Enter three numbers: ");

    scanf("%lf %lf %lf", &num1, &num2, &num3);

    double avg = average(num1, num2, num3);

    printf("The average is: %lf\n", avg);

    return 0;

}

This implementation is similar to the C++ implementation, but it uses the printf and scanf functions instead of cout and cin for input and output.

Python:

//python

Copy code

def average(num1, num2, num3):

    sum = num1 + num2 + num3

    avg = sum / 3

    return avg

num1 = float(input("Enter the first number: "))

num2 = float(input("Enter the second number: "))

num3 = float(input("Enter the third number: "))

avg = average(num1, num2, num3)

print("The average is:", avg)

This implementation takes three float numbers from the user using the input function and then calls the average function to calculate their average. The average function calculates the sum of the three numbers and then divides the sum by 3 to get the average.

Java:

Java:

// java

import java.util.Scanner;

public class Average {

    public static double average(double num1, double num2, double num3) {

        double sum = num1 + num2 + num3;

        double average = sum / 3;

        return average;

    }

    public static void main(String[] args) {

        Scanner scanner = new Scanner(System.in);

        System.out.print("Enter three numbers: ");

        double num1 = scanner.nextDouble();

        double num2 = scanner.nextDouble();

        double num3 = scanner.nextDouble();

        double avg = average(num1, num2, num3);

        System.out.println("The average is: " + avg);

        scanner.close();

    }

}

This implementation is similar to the C++ implementation, but it uses the Scanner class to take input from the user. The average function calculates the sum of the three numbers and then divides the sum by 3 to get the average.
