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

Hello Friends in this article i am gone to share Hackerrank C programming Solutions with you. | 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 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`
