# How to Find Sum of Digits of a Number using Recursion in C++ Full Project For Beginners

Welcome folks today in this blog post we will be `finding sum of digits of a number using recursion in c++`

All the full source code of the application is shown below.

In order to get started you need to make a `app.cpp`

file and copy paste the following code

`app.cpp`

```
#include<iostream>
using namespace std;
int sum=0,rem[10];
int recc(int,int);
int recc(int n,int i)
{
rem[i]=n%10;
n=n/10;
sum+=rem[i];
if(n>0)
recc(n,i+1);
return sum;
}
int main()
{
int num;
cout<<"Enter any number: ";
cin>>num;
cout<<"Sum of digits: "<<recc(num,0);
return 0;
}
```
