Why two case are failed

#1

#include <bits/stdc++.h>
using namespace std;

int reverse(int n)
{
int rev = 0;
while (n != 0) {
rev = (rev * 10) + (n % 10);
n /= 10;
}
return rev;
}

void getSum(int n)
{
n = reverse(n);
int sumOdd = 0, sumEven = 0, c = 1;

while (n != 0) {

    
	if(c==0){
		sumEven += n%10;
	}
    if (c % 2 == 0)
        sumEven += n % 10;
    else
        sumOdd += n % 10;
    n /= 10;
    c++;
}


cout << sumEven<<"\n";
 cout << sumOdd;

}

int main()
{
int n;
cin>>n;
getSum(n);

return 0;

}

#2

hey, try this–>

#include <iostream>
using namespace std;
int main() {
    int n;
    cin>>n;

    int pos = 1;
    int odd_sum = 0;
    int even_sum = 0;

    while(n > 0){
        int x = n%10;
        n = n/10;
        if(pos%2 == 1){
            odd_sum += x;
        }
        else{
            even_sum += x;
        }
        pos++;
    }
    cout<<odd_sum<<endl;
    cout<<even_sum<<endl;
}
