    Re: virtual function in derived class

    Your declaration of f in D is an overload, not an override. If I remember correctly, it even hides the virtual function f inherited from C.

    What's the "right function" to invoke for the D object...
  2. Re: Why is my class showing up as a absract class

    Neither BaseEntity nor Entity are abstract classes since they don't have any pure virtual member functions (or even any virtual member functions, for that matter).

    What I'm curious about is...

    Re: sort vector of struct

    No, I think ordinary functions are allowed as long as they take the two required parameters and return bool according to the strict weak ordering requirement. The advantage of a function object lies...

    Ah, pardon the lack of clarity: I meant "faster" as in "faster feedback". That is, if you have a question like "will this code below produce this result?", you'll get faster feedback on your question...

    Re: sort vector of struct

    The comparator is required to model a "less than" comparison, or what they call comparing for "strict weak ordering". What this means is that if A "less than" B is true, then B "less than" A must be...

    Re: switch{case}

    If you mean '0' to '9' then yes due to fallthrough, but for this kind of question it is usually faster to write a test program and see for yourself.

    Re: pass to function

    This is unnecessarily convoluted:

    volo *app = new volo(cod, n, c);
    flight.push_back(*app);
    delete app;
    It would suffice to write:

    flight.emplace_back(cod, n, c);
    Even if you had to compile...

    Re: Palindromes in Python

    Yes, but C++ has a richer library of generic algorithms, and in this case the next function is more akin to the overly generic std::for_each than to a more descriptive generic algorithm. If you look...

    Re: Remove Whitespaces from the string

    If you want to specifically remove spaces from a string s, then the simplest option would be:

    s.replace(' ', '')
    If you want to remove whitespace in general, then aakashdata's first example would...

    Re: Palindromes in Python

    Yes, I agree. My point is that it's also possible to over-engineer to handle things that don't matter, and in general we should be aware of that too.


    I initially took this as a snide remark,...

    Re: Palindromes in Python

    Sure, but by and large for the kind of strings that people want to check if they are palindromes, this doesn't matter: they are so short that O(N) complexity is meaningless versus amortised O(1)...

    Re: struct to vector

    If you tested the code, you would have found out that you have a typo on this line:

    pp.pushback(temp);
    It should have been:

    pp.push_back(temp);


    You're probably going to use a loop, so...
  15. Re: Is it possible to send verbose o/p of gcc to text file instead of standard output

    Wouldn't normal input redirection work? Say:

    Re: Destructor

    It might be helpful if you printed the addresses of the objects as well, and implemented the copy constructor see it being invoked:

    using namespace std;

    Re: friend function

    Why can't it be a member function that takes no arguments? It also, looks like you can just use std::swap to implement the function.

    I note that your Insieme constructor implementation looks...

    It depends on what does "conversion to int" mean for your class. Once you can clearly define what it means for your class, you can then define it in code. Sometimes (or rather quite often)...
