How do I make a classs istance variable take unlimited arguments in c ?-CodePudding

I am recreating a class list data structure in c with every feature that comes to mind, for educational purposes. I was wondering if there was a way to allow the user to use this sintax:

list my_list = {1, 2, 3, 4, 5};

or even this sintax if possible (I don't think it is but I'll ask anyways)...

list my_list = [1, 2, 3, 4, 5];

Let me know if the only way to do this is to mess with the compiler and it can't be done with operator overloading.

CodePudding user response：

This is what initializer lists are for. You could for example have a constructor like this:

class list {
public:
    list(std::initializer_list<int> &l) {
        for (int x : l) {
            // do something with x
        }
    }
};

Or making it more generic by using templates:

template<typename T>
class list {
public:
    list(std::initializer_list<T> &l) {
        for (auto x : l) {
            // do something with x
        }
    }
};
