Explanation:

What is the algorithm for finding the greatest of three numbers?

The Algorithm for finding the greatest of three numbers :-

Step 1 : Start the program .

Step 2 : Declare variable a, b, c, largestValue.

Step 3 : If a > b go to step 4 Otherwise go to step 5

Step 4. If a > c SET largestValue = a Otherwise largestValue = c

Step 5 : If b > c SET largestValue = b Otherwise largestValue = c

Step 6 : End.

1.Implementation of the Algorithm using Java :

2.package conditionalStatements;

import java.util.Scanner;

3.

4.public class LargestValue{

5.

6.Public static void main(String [] args){

7.

8.Scanner sc = new Scanner(System.in);

9.

10.int a,b,c,largestValue;

11.

12.System.out.print("a = ");

13.a = sc.nextInt();

14.

15.System.out.print("b = ");

16.b = sc.nextInt();

17.

18.System.out.print("c = ");

19.c = sc.nextInt();

20.

21.if(a>b){

22.if(a>c){

23. largestValue = a;

24. }else{

25. largestValue = c;

26. }

27.}else{

28. if(b>c){

29. largestValue = b;

30. }else{

31. largestValue = c;

32 }

33.}

34.System.out.println("Largest among three numbers is = "+largestValue);

35. }

36.}
