Question

Program – version 1: Sum of Range ^_Algorithm

Write a program that will sum the integers between a given range (limit your range from 0 to 50). For example, if the user want to add the integers between (and including) 1 and 10, then the program should add:

1 + 2 + 3 + 4 + 5 + 6 + 7 + 8 + 9 + 10

Algorithm:

1. Program title/description
2. Ask the user to input a start value in the range 0 to 50. Remember to create the user prompts.
3. Ask the user to input a stop value in the range 0 to 50. (NOTE: the stop value should be greater than the start value) Remember to create the user prompts.
4. Use a loop to iterate through the integers in the range, adding to the sum each time the loop executes.
5. Output the start value, stop value, and the sum of the integers in between.

Test data (Use this data to test to ensure your program does the math correctly.):

• Start value: 1
• Stop value: 10
• Sum: 55

Answer 1

Required program in java -->

import java.util.Scanner;
public class Main
{
   public static void main(String[] args) {
   Scanner scanner = new Scanner(System.in);
   int sum=0; // declare variable sum and initialize it with 0
System.out.println("Start Value: "); // ask user for start value
int start = scanner.nextInt(); // read input from user and store the value in start
System.out.println("End Value: "); // ask user for end value
int end = scanner.nextInt(); // read input from user and store the value in end
if(start<end && start>=0 && start<=50 && end>=0 && end<=50){ // if all the conditions satisfies
for(int i=start; i<=end; i++){ // for loop executes from i= start to i=end
sum=sum+i; // value of i is added in sum
}
System.out.println("Sum : "+sum); //print "Sum : " (value of sum)
   }
   }
}
