Here is code in java.
import java.util.*; // import package
class Main // creating class
{
public static void main (String[] args) // main method
{
Scanner br=new Scanner(System.in); // scanner class for input
int []a=new int[20]; // declaring array
int count=0,x,j; // creating variable
int sum =0;
System.out.println("Enter a weight (0 to stop):");
x=br.nextInt(); // taking input
while(x!=0) // iterating over the loop
{
a[count] = x;
count++;
System.out.println("Enter a weight (0 to stop):");
x=br.nextInt();
}
for( j=0;j<count;j++) // iterating over the loop
{
sum+=a[j];
}
double avg = sum/(double)count;
System.out.println("The total is: "+sum);
System.out.println("The average is: "+avg);
System.out.println("Here are all the numbers less than the average: ");
for( j=0;j<count;j++) // // iterating over the loop
{
if(a[j]<avg)
System.out.print(a[j]+" ");
}
}
}
Explanation:
First create an object of "Scanner" class to read input from the user.
Create an array of size 20, which store the number given by user.Ask user
to give input and keep the count of number in the variable "count". If user
give input 0 then it will stop taking input.And then calculate sum of all the
input.It will calculate average by dividing the sum with count and print it.
It will compare the all elements of array with average value, if the element
is less than average, it will print that element.
Output:
Enter a weight (0 to stop):
1
Enter a weight (0 to stop):
2
Enter a weight (0 to stop):
3
Enter a weight (0 to stop):
4
Enter a weight (0 to stop):
5
Enter a weight (0 to stop):
6
Enter a weight (0 to stop):
7
Enter a weight (0 to stop):
8
Enter a weight (0 to stop):
9
Enter a weight (0 to stop):
10
Enter a weight (0 to stop):
0
The total is: 55
The average is: 5.5
Here are all the numbers less than the average:
1 2 3 4 5
