Will you please help me in this code , because this shows that did you account for negative values?

#1

#include
using namespace std ;
int main()
{
int num;
cin>>num;
int n,i=0;
while(num>0)
{
n=num%10;
if(n==0)
{
n=5;
}
i = (i10)+n;
num=num/10;
}
int j=0;
while(i>0)
{
n=i%10;
j= (j10)+n;
i=i/10;
}
cout<<j;
return 0;
}

hi @deepshreyamishra301_1918130c8477386b
refer this–>

#include <iostream>
using namespace std;

long long int reverse(long long int num)
{
    long long int rev=0, rem;
    while(num!=0)
    {
        rem=num%10;
        rev=rev*10+rem;
        num/=10;
    }
    return rev;
}
long long int replacezero(long long int n)
{
    long long int digit, result=0;
    if (n==0){
        return 5;
    }
    else{
        while (n!=0){
            digit=n%10;
            if (digit==0){
                digit=5;
            }
            result=result*10+digit;
            n/=10;
        }
        return reverse(result);
    }
}

int main()
{
    long long int num;
    cin>>num;
    cout<<replacezero(num)<<endl;
}
