具有常数 class 成员的赋值运算符

Question

I have a class called RSArray which contains a constant data member. But for this class I want to create a custom assignment operator. See code below: -

class RSArray
{
private:
    int *data;
    const int max_size;
public:
    RSArray(size) : max_size(size)
    {
        data = new int[max_size];
    }
    RSArray &operator=(const RSArray &src)
    {
         data = new int[src.max_size];
         max_size = src.max_size
    }

}

int main()
{
    RSArray one(10), two(15);
    one = two;
}

The above code giving me error when assignment operator is called because we can't change value of a const data member.

Is there any other way to get rid of this error?

Yes, remove the const from max_size . Assignment by definition mutates the target.
