C++11 variable number of arguments, same specific type


Question is simple, how would I implement a function taking a variable number of arguments (alike the variadic template), however where all arguments have the same type, say int.

I was thinking about something alike this;

void func(int... Arguments)

Alternatively wont a recursive static assert on the types work?


Solution

  • A possible solution is to make the parameter type a container that can be initialized by a brace initializer list, such as std::initializer_list<int> or std::vector<int>. For example:

    #include <iostream>
    #include <initializer_list>
    
    void func(std::initializer_list<int> a_args)
    {
        for (auto i: a_args) std::cout << i << '\n';
    }
    
    int main()
    {
        func({4, 7});
        func({4, 7, 12, 14});
    }
