Question

I need help finishing this portion of my code. Will someone show me the code with some explanation please?:

BigInt& BigInt::operator+=(const BigInt& num2)
{
if(_digits.size()<num2._digits.size())
    _digits.resize(num2._digits.size(),0);

    for(int idx=0; idx<_digits.size(); idx++)
    {
      int right_digit;
      if (idx < num2._digits.size())
        right_digit = num2._digits[idx];
      else
        right_digit = 0;                                                      
      // I need help here. Each one of these indexes hold a single int        
      // It needs to loop through and add all of the index values              
      // If the value of the sum is greater than 9                             
      // Then a carry must be applied to the next sum                          
      // After the last two ints are added and there is a carry                
      // Then the _digits vector needs to be increased by one and              
      // The carry will be placed in this index.                               
      int carry = 0;
      _digits[idx] = _digits[idx]+right_digit+carry;

    }


}
