Question

With the defined function as…

void func (int a [3]) { ... }

I’d like to be able to pass a dynamic static array like so

func (new int [3] {1,2,3});

instead of…

int temp [3] = {1,2,3};
func(temp);

Is this possible with C++?

Answer 1

If you have a C++11 compiler, func (new int [3] {1,2,3}); would work fine (but, remember that you are responsible for deleteing the memory). With gcc, just pass the -std=c++11 flag.

However, look into std::array so you don’t have to use new:

Example

void func (std::array<int, 3> a)
{
}

int main()
{
    func({{1, 2, 3}});
}
