C++ get each digit in int

Question

I have an integer:

int iNums = 12476;

And now I want to get each digit from iNums as integer. Something like:

foreach(iNum          


        

Answer 1

My solution:

void getSumDigits(int n) {
    std::vector<int> int_to_vec;
    while(n>0)
    {
        int_to_vec.push_back(n%10);
        n=n/10;
    }

    int sum;

    for(int i=0;i<int_to_vec.size();i++)
    {
        sum+=int_to_vec.at(i);

    }
    std::cout << sum << ' ';
}
