C :

int main(int argc, const char * argv[]) {

    int data;
    int count = 0;
    int sum = 0;
    scanf("%d",&data);
    while (data) {
        sum += data%10;
        data /= 10;
        count++;
    }
    printf("%d\n%d\n",count,sum);
    
}

C++ :

#include<bits/stdc++.h>
using namespace std;
int n;
int s,t;
int main()
{
	cin>>n;
	while(n!=0)
	{
		s++;
		t+=n%10;
		n/=10;
	}
	cout<<s<<endl<<t;
	return 0;
}
