Hello, I am trying to add two arrays

[n3wb86]

hello,

I am trying to add two arrays and print the outcome; the outcome is correct, but when i use my print function the outcome differs. Any hints or help would be much welcome.

#include <iostream>
#include <string>
#include <sstream>
#include <cstdlib>
#include <iomanip>

using namespace std;

void add(int a[], int b[], int result[]);
void print(int a[]);

int main()
{
    int op1[5] = {0,2,7,8,9};
    int op2[5] = {0,5,1,3,4};
    int result[5]= {0};

    add(op1,op2,result);
    //print(op1);
    //print(op2);
    print(result);
    //for (int i = 0; i < 5; i++)
    //cout << result[i] << " " << endl;
}
void add(int arr[], int b[], int result[]){
    int carry = 0;
    int sum = 0;

    for (int i = 4; i >= 0; --i){
	sum = arr[i] + b[i] + carry;

	cout << "sum == " << sum << endl;
        if (sum >= 10) {
	    sum = arr[i]/10;
	    carry = 1;
        }
        else {
	    carry = 0;
	}
	result[i] = sum + arr[i-1];
    }
}
void print(int arr[])
{
    for (int i = 4; i >= 0; --i) 
	cout << arr[i] << endl; 
}

Thank you.
