Java Exercises: Compute the digit number of sum of two given integers

Java Basic: Exercise-212 with Solution

Write a Java program to compute the digit number of sum of two given integers.

Input:

Each test case consists of two non-negative integers a and b which are separated by a space in a line. 0 ≤ a, b ≤ 1,000,000

Pictorial Presentation:

Java Basic Exercises: Cmpute the digit number of sum of two given integers.

Sample Solution:

Java Code:

import java.util.*;
public class Main 
{
    public static void main(String[] args) 
    {		
        System.out.println("Input two integers(a b):");
        Scanner stdIn = new Scanner(System.in);
            int a = stdIn.nextInt();
            int b = stdIn.nextInt();
            int sum = a + b;
            int count = 0;
            while(sum != 0)
            {
                sum /= 10;
                ++count;
            }
            System.out.println("Digit number of sum of said two integers:");
            System.out.println(count);
    }
}

Sample Output:

Input two integers(a b):
 13 25
Digit number of sum of said two integers:
2
