Question

Write a program to accept a 5 digits number using the concept of function argument of main ( ) method and find out the sum of first digit, middle digit and last digit of that 5 digit number. Display the results with proper message. Example: N = 10238 Sum is 1 + 2 + 8 = 11

Answer 1

Program in Java :-

import java.util.Scanner;

public class FiveDigits {

public static void main(String [] args) {

Scanner sc = new Scanner(System.in);

System.out.print("Please enter a five digit number : ");

int n = sc.nextInt();

if (n <= 99999 && n >= 10000) {

int firstDigit = n / 10000;

int middleDigit = (n / 100) % 10;

int lastDigit = n % 10;

int sum = firstDigit + middleDigit + lastDigit;

System.out.println("Sum is " + firstDigit + " + " + middleDigit + " + " + lastDigit + " = " + sum);

}

else {

System.out.println("Invalid");

}

sc.close();

}

}
