Sum of Digits of a Five Digit Number in C - HackerRank Solution

Hello coders, today we will be solving Sum of Digits of a Five Digit Number in C    HackerRank Solution.

Objective 

The modulo operator, %, returns the remainder of a division. For example, 4 % 3 = 1 and 12 % 10 = 2. The ordinary division operator, /, returns a truncated integer value when performed on integers. For example, 5 / 3 = 1. To get the last digit of a number in base 10, use 10 as the modulo divisor.

Task

Given a five digit integer, print the sum of its digits.

Input Format

The input contains a single five digit number, n.

Constraints

10000  ≤ n  ≤ 99999

Output Format

Print the sum of the digits of the five digit number.

Sample Input 0

10564

Sample Output 0

16
