here is the implementation for >> and operator+ for bigint

std::istream& operator>> (std::istream& in, bigint& num)
{
        num.initialize();
        char ch;
        in >> ch;
        while (ch != ';')
        {
                num.push_back(ch-'0');
                in >> ch;
        }
        return in;
}


bigint bigint::operator+ (bigint rhs) const
{
        bigint result;
        int rhs_max = rhs.size();
        int lhs_max = size();
        int max;
        if (rhs_max > lhs_max)
                max = rhs_max;
        else
                max = lhs_max;
        int idx = 0;
        int temp;
        while (idx < max)
        {
                temp = digits[idx] + rhs.digits[idx] + result.digits[idx];
                int i = 0;
                while (temp != 0)
                {
                        result.digits[idx+i] = (temp&#37;10);
                        temp = (temp/10);
                        ++i;
                }
        ++idx;
        }
        return result;
}

I appologize for not using the code tags (new here) and its been a very long week so im a little out of it
