Inline initialization of an array

Question

I have this struct:

struct Foo {
    int a;
    int* b;
};

Then I'm creating an instance for it like this:

int x [] = { 5, 6 };
Foo y = { 2, x };

But, I'd like to create the x array inline, maybe something like this:

struct Foo y = { 2, (int[]) { 5, 6 } };

But the example above do not work... How can I achieve this?

--------- EDIT:

I'm getting this error from intellisense:

cast to incomplete array type "int []" is not allowed

Build error:

Error C4576 a parenthesized type followed by an initializer list is a non-standard explicit type conversion syntax

I'm using Visual Studio 2015 (v140).

Answer 1

In your case, Foo is not a type.

Try

struct Foo y = { 2, (int[]) { 5, 6 } };

It works as expected

Edit:

You only need to free() the memory programatically which you allocate using the allocator function (malloc() and family). The memory which is not returned by an allocator function, need not be free()-d by the programmer.
