Program to print the average of n numbers

The average is the outcome from the sum of the numbers divided by the count of the numbers being averaged.

For example: 1,2,3,4,5

Number of all elements = 5

Sum of all elements = 1+2+3+4+5 =15

Average = Sum of all elements / number of all elements = 15/5 =3

Average =3

Algorithm

STEP 1: START
STEP 2: DEFINE n.
STEP 3: SET count = 1
STEP 4: DEFINE xF, averageF
STEP 5: SET sumF = 0
STEP 6: ENTER n
STEP 7: REPEAT STEP 8 to 10 UNTIL count<=n
STEP 8: Enter xF
STEP 9: sumF += xF
SETP 10: count = count + 1
SETP 11: SET averageF = sumF/(n-1)
STEP 12: PRINT averageF
STEP 13: END

Java Program

import static java.lang.Float.sum;
import java.util.Scanner;
public class Average {
   public static void main(String[] args)
    {
      int n, count = 1; 
      float  xF, averageF, sumF = 0; 
      Scanner sc = new Scanner(System.in);   
      System.out.println("Enter the value of n");
      n = sc.nextInt();
      while (count <= n) 
             { 
                  System.out.println("Enter the "+count+" number?");
                  xF = sc.nextInt();
                  sumF += xF; 
                  ++count; 
             } 
                  averageF = sumF/n; 
        System.out.println("The Average is"+averageF);
    }  
}

Output:

Enter the value of n
5
Enter the 1 number?
1
Enter the 2 number?
2  
Enter the 3 number?
3
Enter the 4 number?
4
Enter the 5 number?
5
The Average is 3.0

C program

#include<stdio.h>
void main( ) 
{ 
  int n, count = 1; 
  float x, average, sum = 0; 
  printf("Enter the value of n?");
  scanf ("%d",&n); 
  while (count <= n) 
     { 
      printf ("Enter the %d number?",count); 
      scanf("%f", &x); 
      sum += x; 
      ++count; 
     } 
      average = sum/n; 
      printf("\nThe Average is %f\n", average); 
}

Output:

Enter the value of n? 5
Enter the 1 number? 1
Enter the 2 number? 2
Enter the 3 number? 3
Enter the 4 number? 4
Enter the 5 number? 5

The Average is 3.0000

Python program

n = int(input("Enter the value of n?"))
sum=0
count = 1
while (count<=n):
    x = int(input("Enter the %d number?"%(count)));
    sum = sum + x;
    count=count+1;
average  = sum / n;
print("Average using a while loop ", average)

Output:

Enter the value of n? 5
Enter the 1 number? 1
Enter the 2 number? 2
Enter the 3 number? 3
Enter the 4 number? 4
Enter the 5 number? 5
Average using a while loop   3.0000

Php program

<?php
$count=1;
$sum = 0;
$average=0;
echo "Enter the value of n?";
$n = readline();
while($count<=$n)
{
echo "Enter the number";
$x = readline();
$sum = $sum+$x;
$count=$count+1;
}
$average=$sum/$n;
echo $average;
?>

Output:

Enter the value of n? 5
Enter the number 1
Enter the number 2
Enter the number 3
Enter the number 4
Enter the number 5
3.0000

C# program

using System; 
public class Average
{
   public static void Main()
    {
       int userInput;
	   int  n, count = 1; 
      float  x, average, sum = 0; 
      Console.WriteLine("Enter the value of n?");
      n=Convert.ToInt32(Console.ReadLine());
      while (count <= n) 
             { 
                  Console.WriteLine("Enter the "+count+" number?" ); 
                  userInput = Convert.ToInt32(Console.ReadLine());
                  sum += userInput; 
                  ++count;
             } 
                  average = (float)sum/(n); 
                  Console.WriteLine("\nThe Average is %f\n");
	   Console.Write(average);	   
}}

Output:

Enter the value of n?
5
Enter the 1 number?
1
Enter the 2 number?
2  
Enter the 3 number?
3
Enter the 4 number?
4
Enter the 5 number?
5
The Average is 3.0
