Arpit Mandliya In this post, we will see how to find sum of digits of number in java. You can find unit’s place digit by number%10, add it to the total and divide the number by 10 to remove the unit’s place. 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 ...
One of the common programming practice question thrown to beginners is to write a program to calculate the sum of digits in an integral number. For example, if the input is 123456 then output or sum of the digit is (1+2+3+4+5+6) = 21. An additional condition is you can not use ...
It initializes an integer variable 'sum' to store the sum of the digits, starting with 0. It enters a while loop that continues as long as 'n' is not equal to 0. Inside the loop, it calculates the last digit of 'n' using the modulus operator (n % 10) and adds it to the 'su...
{ int n, pro; n = num; //keep value of num safe pro = 1; while (n > 0) { pro *= (n % 10); //find digit using n=n%10 n /= 10; } return pro; } //End of productDigits() } public class Main { public static void main(String[] s) { DigitsOpr dig = new D...
Note that the value of digit will be modified in subsequent iterations. Thus, we should immediately add it to variable sum used to store the sum of digits. The variable sum should be initialized to zero before the loop. The program segment given below determines the sum of digits of the ...
sum+=(num%10); //add digit into sum SumOfDigits(num/10); } return sum; } In the above code, we created a global variablesumwith the initial value 0, and we implemented a recursive functionSumOfDigits()that accepts a number and returns the sum of all digits to the calling ...
