   • #define (CLASS) in c++

     The backslashes are there to "protect" the newline -- the preprocessor will throw away both the \ and the newline when reading in the file, putting the entire thing on one logical line. (Well, it'll also emit #line markups so the compiler can generate decent error messages too.)

     Someone thought that layout was more legible than this:

     #define A(CLASS) B(CLASS) void *D(const C*to);

     If you imagine that B, D, and C are probably replaced with something else in the file, it'll look a bit like this in the output:

     Monkey(Simian) void *Bananas(const sticks *to);

     It must have made more sense to them, as they wrote the macro, to instead "see" it like this:

     Monkey(Simian)void *Bananas(const sticks *to);

     I'm not sure it is an improvement (and I think I hate the style), but hopefully it makes sense now.

   • define static string variable in c++ class

     Top Answer

     Answered Feb 29, 2012 · 7 votes

     Why is this possible for an int variable: [..] but for a string variable I need to do it this way?

     Just because. Actually you can still make the string const but, yes, you have to define it outside of the class definition. You can only do in-place initialisation of static members when they are const and integral (or "of literal type").

     (In C++11 you can even do it for non-static non-const members when they are of literal type.)

     I would like that for every object of class foo there were just one instance of foo::string, representing a const value that should never change. Is there another way to solve this problem?

     A static const std::string, as you might expect.

     // C++03struct T { static const std::string foo;};const std::string T::foo = "lol";

     Have you missed out a <T> from one of your function definitions? I.e. have this:

     template <class T>bool Stack::isempty()-

     instead of this:

     template <class T>bool Stack<T>::isempty() ^^^

   • Define norm as member function of vector class in C++

     Top Answer

     Answered Nov 06, 2020 · 3 votes

     You are declaring norm() as a friend function, so it is not actually a member of the vector class itself. You are telling the compiler that some external non-member function T norm() is a friend of vector so that it can access vector's private members. But then you don't actually define such a T norm() function!

     The correct way to implement norm() as a member, with a definition outside of the class declaration, would look like this instead:

     template <typename T>class vector{ ...public: ... T norm(); // <-- remove 'friend'!};template <typename T>T vector<T>::norm(){ // <-- note the extra <T>! T sum{0}; for (auto i = 0u; i < _size; ++i){ sum += elem[i]; } return std::sqrt(sum);}

     On a side note:

     You might consider using SFINAE to omit the declaration+definition of norm() for T types that std::sqrt() does not support (non-integers/floating-point types, like strings, etc).

     Also, your vector class does not implement the Rule of 3/5/0 to manage its inner array properly. You need to add proper copy/move constructors and copy/move assignment operators to it.

   Dec 12, 2013 · iterate repeats a process that can be applied at each step of a traversal. or. for any subject with a collection of entries: traverse: go through the entries and cover the whole subject. iterate: repeat a process, which can be for each entry as you traverse something.

   Is STD a base class or a iterator class?

   • std::iterator is a base class only, its basically a container for some traits, but if you wanted to use it to implement your own iterator class you'd need to derive from it. However you don't need to use it, there was a proposal to deprecate it, you could just define those traits directly in an iterator that you write.

   What is an iterator in Java?

   • With many classes (particularly lists and the associative classes), iterators are the primary way elements of these classes are accessed. An iterator is best visualized as a pointer to a given element in the container, with a set of overloaded operators to provide a set of well-defined functions:

   How does an iterator work?

   • Once the appropriate type of iterator is created, the programmer can then use the interface provided by the iterator to traverse and access elements without having to worry about what kind of traversal is being done or how the data is being stored in the container.

   A range-based for loop only requires that your class have begin() and end() methods (or overloads of std::begin() and std::end()) that return iterators. It doesn't care where those iterators come from. So, the simplest solution is to just use the array's own iterators instead of trying to define your own, eg:

    Feb 28, 2024 · Iterators play a critical role in connecting algorithm with containers along with the manipulation of data stored inside the containers. The most obvious form of an iterator is a pointer. A pointer can point to elements in an array and can iterate through them using the increment operator (++).
