Question

Iven an array temps of double s, containing temperature data, compute the average temperature. Store the average in a variable called avgTemp. Besides temps and avgTemp, you may use only two other variables -- an int variable k and a double variable named total, which have been declared .
k = 0;
total = 0;
while (k < temps.length)
{
total = total + temps[k];
k++;
}

avgTemp = total / (temps.length);

Answer 1

Answer:

import java.util.Arrays;

import java.util.Scanner;

public class num1 {

   public static void main(String[] args) {

       Scanner in = new Scanner(System.in);

       System.out.println("Enter length of the array:");

       int len = in.nextInt();

       double [] temps = new double[len];

       double avgTem;

       int k =0;

       double total = 0;

       for( k=0; k<temps.length; k++){

           System.out.println("Enter values for the array");

           temps[k]=in.nextDouble();

       }

       System.out.println("The Arrays contains the following values");

       System.out.println(Arrays.toString(temps));

       // Computing the average of the values

       for(k=0; k<temps.length; k++){

           total = total+temps[k];

       }

       avgTem = total/(temps.length);

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

   }

}

Explanation:

• Using Java programming language
• Import the Scanner class to receive user input
• Prompt User for the length of the Array, receive and store in a variable len;
• Declare a new double array of size len double [] temps = new double[len];
• Using a for loop, continually prompt user to enter values into the array
• Display the values of the array using Java's Arrays.toString method
• Use another for loop to add up all the elements in the arraay and store in the variable called total
• Outside the second for loop calculate the average avgTem = total/(temps.length);
• Display the average temp.
