How to generate number with 3 digit from list of number by c++?

Question

I'm a new programmer, and want to generate array of number with 3-digits from number list (2,5,8). I have created a code, but the output is not my expected result. This is my simple code:

int main()
{
    int arr[3]={2,5,8};

    int d=3;
    int times=1;

    for (int a:arr){
        int sum = a;
        for (int i=1; i<d; i++){
            times *= 10;
            sum += a*times;
        }
        cout<<sum<<endl;
        sum=0;
    }

    return 0;
}

My expected the result of 222,555 and 888, but the actual output is 222,55005 and 8800008.

It will help probably. You forget to reset times variable

int main()
{
    int arr[3]={2,5,8};

    int d=3;
    int times=1;

    for (int a:arr){
        int sum = a;
        for (int i=1; i<d; i++){
            times *= 10;
            sum += a*times;
        }
        cout<<sum<<endl;
        times = 1;   //<---added
        sum=0;
    }
    return 0;
}
