We just replaced the While loop in the above Java sum of digits example with the For loop. Programmers usually use loops to execute a set of statements. Here Number = 0 so, the condition present in the while loop will fail. Divide the number by 10 with help of ‘/’ operator it means it execute the code five times. Use another variable instead of i which is the loop variable: int i = 1; int sum = 0; while (i < 101) { sum += i; i++; } Now sum will contain the desired output. The concept of the sum of digits is: The positive numbers 1, 2, 3... are known as natural numbers and its sum is the result of all numbers starting from 1 to the given number. It's because the number of iterations is known. While iterating we will extract the digit from each position and then add them to the previously extracted digit, thus getting the sum.

Program to Find Sum of Digits in Java using Functions. In the following PHP program factorial of number 5 is calculated. In our general life, we are not gonna use such a kind of program but it can be a good exercise for beginners to better understand the PHP loops concept its a very good beginning program. The concept of the sum of digits is: An integer number of 4 digits is 2368 ==> 2 + 3 + 6 + 8 ==> 19 . The main idea to find sum of digits can be divided in three steps. Here we first divide our given number into individual digits and then add them all. Extract last digit of the given number. If we find mod of any number by 10 then the result is the last digit of the number. Example: Code: =1;$i--) { // multiply each number up to 5 by its previous consecutive number $fact = $fact * $i; } // Print output of th… 3) Repeat these two steps sum=sum+n%10; n/=10; until n!=0, if n=0 then while terminated and print the sum value. This Java program allows the user to enter the size and Array elements. To find the sum of numbers from 0 to N, we use a mathematical formula: N(N+1)/2. Examples: Input: 123456 Output: 21 Input: 9874 Output: 28 Approach is to take a number and getting each digit with MOD function and summing it up.
