## Description

## What is sum of digit?

We can get the **sum of the digit** by adding every digits of the given number forgetting the place of value of the digit.

For example:

if we have the number: 382

We can calculate the **digit sum** as 3 + 8 + 2 = 13.

## Algorithm of the sum of digit.

Step 1: Get number by user.

Step 2: Calculate the remainder of the number.

Step 3: sum of the remainder.

Step 4: Divide by the 10 (for remove the digit).

Step 5: REPEAT the step 2, step 3 and step 4 while the number is not equal to zero (n!=0).

## Sum of digit program in c programming language.

```
#include<stdio.h>
int main(){
int n;
printf("Enter the number : ");
scanf("%d", &n);
int sum = 0, x;
while(n!=0){
x = n % 10;
sum = sum + x;
n = n / 10;
}
printf("Sum is : %d",sum);
return 0;
}
```

## Sum of digits c++

```
#include<iostream>
using namespace std;
int main(){
int n;
cout<<"Enter the number : ";
cin>>n;
int sum = 0, x;
while(n!=0){
x = n % 10;
sum = sum + x;
n = n / 10;
}
cout<<"Sum is : "<<sum;
return 0;
}
```

Output :

Enter the number: 123

Sum is : 6
