# Find Sum of all Digits of a Number

**Objective**: Given a number, find the sum of all of the digits in the number.

**Example**:

Number = 3045 Sum = 3+0+4+5 = 12 Number = 231 Sum = 2+3+1 = 7

**Approach**:

- Initialize sum =0.
- While number is greater than 0
- Divide the number by 10 and Add remainder the sum

N = 123, Sum = 0 N = N/10 => 123/10, N = 12, remainder = 3, sum = 3 N = N/10 => 12/10, N = 1, remainder = 2, sum = 3+2 = 5 N = N/10 => 1/10, N = 0, remainder = 1, sum = 3+2+1 = 6

**Java Code**:

**Output**:

Sum of digits of number 3045 is: 1
